City of York v Trinity One (Leeds) Ltd

These are cross appeals against the orders of David Halpern QC sitting as a deputy judge of the High Court which were made on 8 March 2017. The appeals arise out of a claim by the Council of the City of York (“the Council”) to recover a sum of money from Trinity One (Leeds) Limited (“TOL”) in lieu of the provision of affordable housing by TOL within a residential development approved by the Council. The sum fell due under an agreement made on 6 October 2003 in accordance with section 106 of the Town and Country Planning Act 1990 (“the Agreement”). There is a separate appeal to the Secretary of State under section 106BC of the 1990 Act the merits of which are not before this court but which is relied upon in the alternative by TOL to reduce or extinguish its liability.

In his judgment, the judge identified two issues:

On the first issue, the judge found that TOL was liable to the Council although not in the sum claimed. The Council obtained judgment in the sum of £553,058 together with interest in the sum of £65,533.70: in total a sum of £618,591.70. On the second issue, the judge found that TOL would “be released from [the obligation to pay money], if and to the extent that the Secretary of State allows its appeal under section 106BC”. The judge made a declaration in accordance with his conclusion. TOL was ordered to pay 50% of the Council’s costs of the claim. TOL appeals against the judge’s conclusion on liability and quantum and the Council appeals against the declaration as to the effect of the section 106BC appeal to the Secretary of State. The judge granted permission to appeal the two relevant paragraphs of his order.

There is a detailed factual background set out at paragraphs 17 to 35 of the judgment below which I gratefully adopt. I shall highlight what follows so that this judgment can be understood.

On 6 October 2003 the then-owner of land at 187 Tadcaster Road, York (“the Site”) entered into the Agreement by which a proportion of the housing to be constructed on the Site in accordance with outline planning permission granted on the same date was to be delivered as affordable housing units. In default of on-site provision, the Agreement required the owner to pay the Council commuted sums, on the sale of each of the affordable housing units on the open market.

The Site was acquired by TOL in 2004. Development commenced in 2005. In September 2006 TOL advised the Council that it had discharged its obligation to offer the affordable units to registered social landlords without success, and invited the Council to propose a commuted sum which should be paid. The affordable units were subsequently sold on the open market on various dates between September 2007 and August 2014.

The dispute between TOL and the Council centres on the wording of paragraphs 6.12.1 and 7.8.3 of Schedule 1 to the Agreement, which set out the method by which the commuted sums were to be calculated. Schedule 1 to the Agreement is inconsistent in its internal references to paragraphs and clauses but nothing turns on that and although there are slight variations in the wording of paragraphs 6.12.1 and 7.8.3, the core language of the paragraphs states that the commuted sum:

“shall be calculated on the amount of Social Housing Grant necessary to secure affordable rented homes of an equivalent type and size on another site [in a similar residential area in the City of York] which grant for the avoidance of doubt shall be calculated at normal grant levels from regional TCI tables provided on an annual basis by the Housing Corporation or such equivalent grant calculation current at the time and supported by the Housing Corporation”

And “Social Housing Grant” is defined by clause 2.1.23 as:

“the grant that may be provided in respect of affordable housing in the Council’s administrative area in accordance with Government and Housing Corporation Guidance.”

The commuted sum has been in issue between the parties since 2006. TOL denies that any sum falls due to the Council in accordance with the Agreement because it says that the Agreement does not provide a workable basis for calculating the sum due. The Council maintains that such a result would be perverse and invites the court to construe the relevant clauses to give practical effect to the parties’ agreement.

On 24 April 2013, sections 106BA-BC of the 1990 Act came into force. On 29 April 2016, during the course of the proceedings below, TOL made an application to the Council pursuant to section 106BA to seek to release itself from the obligation to pay a commuted sum under the Agreement. The Council refused that application on 27 May 2016 and TOL appealed against that decision to the Secretary of State for Communities and Local Government in accordance with section 106BC.

On 1 September 2016, TOL amended its defence to the claim in these proceedings, contending that, if its appeal under section 106BC was allowed, then it would not be liable to the Council for any sum otherwise found due under the Agreement. The point was argued at trial. The judge agreed with TOL, and the Council appeals against this part of the Order.

TOL’s appeal under section 106BC was heard on 25 April 2017, and dismissed by a decision letter dated 16 May 2017. However, that decision was successfully challenged by TOL in judicial review proceedings on the basis that the Inspector had made an inadvertent but material error of fact. The decision was quashed and the appeal remitted back for redetermination. A new hearing was listed for 15 March 2018. That has also been determined but the parties do not agree that this court should give any consideration to the contents of the same and it is understood that the redetermination is itself the subject of further judicial review proceedings.

There is a detailed review of the statutory and policy background to these appeals at paragraphs 3 to 16 of the judgment below. The relevant statutory materials are annexed to this judgment.

In summary, it was Government policy at the time of the Agreement that affordable housing would be provided as part of the development of a site. This would be achieved, inter alia, by agreements made in accordance with section 106 of the 1990 Act.

The Council published an Advice Note in September 2000 which set out its policy in relation to affordable housing. The Council stated that it would accept commuted payments in exceptional circumstances. At paragraph 45 of the Advice Note it was stated that the commuted sum would be based on the amount of Social Housing Grant (“SHG”) necessary to secure an affordable home of an equivalent type and size on another site. In turn, this amount was to be calculated from the regional Total Cost Indicator (“TCI”) tables provided on an annual basis by the Housing Corporation.

The Housing Corporation stopped publishing the TCI tables after March 2006, by which time they were no longer used to calculate the SHG. The system changed from a calculation based on inputs to a calculation based on outputs. In April 2011, the system changed again to replace SHG by the Affordable Homes Grant which was also calculated differently.

In order to understand the judge’s careful reasoning, it is helpful to identify the material that he relied upon. There were four witnesses who gave oral evidence to the court:

The judge analysed the contractual clauses in the following way. He concluded that the parties had agreed that:

That analysis is uncontentious. It was common ground between the parties that the grant calculation at (a) (referred to as ‘Part 3(a)’) is no longer relevant as by the time any obligation arose under clause 6.12.1 the SHG regime was no longer in force. That left the parties’ agreement as to the equivalent grant calculation at (b) (‘Part 3(b)’). The judge set out in his judgment the Council’s case and TOL’s case about the construction of the clause and then proceeded to discuss the rival submissions and come to a conclusion.

A summary of that discussion is as follows. The judge noted that the grant calculation at Part 3(a) is inapplicable and Part 3(b) is the only alternative provision in the Agreement. He acknowledged the submission that if Part 3(b) is inapplicable, then nothing is payable to the Council. The judge noted that: (i) after March 2006 there was no “equivalent” to SHG; and (ii) there was no method of calculation which was “supported by the [Housing Corporation]” after March 2003. He concluded, however, that on its true construction a sum is payable under Part 3(b).

The judge reasoned that:

The judge held that this is one of those “very unusual cases” in which one can see from the language of the Agreement that the parties did not focus on the issue that arose which was intended to be covered by Part 3(b). He held that the parties would have intended to substitute whatever would produce the nearest equivalent figure. A literal reading of Part 3(b) would flout business common sense. The judge concluded that Part 3(b) is intended to provide a method of calculation which produces a sum that is as close as possible to the figure that would have been payable, if SHG still existed. The judge used the calculation produced by Mr Parker for the purpose of the proceedings under section 106BC as the basis of quantum.

The second issue involved a consideration of the interrelationship between the Agreement and the new statutory provisions (which were themselves time limited). First, the judge noted that the obligation on TOL to make payments under the Agreement arose no later than 2014. Second, the judge noted that the application under section 106BA was made on 29 April 2016 (the final day on which that section was in force). He framed the issue as whether TOL would be discharged from its accrued obligation to make a payment in lieu of providing affordable housing if its appeal to the Secretary State was successful.

The Council’s argument was that legislation does not usually take away accrued rights, and Parliament had not intended to do so when enacting sections 106BA and 106BC. TOL’s argument was that the phrases “is to have effect” in section 106BA(10) and “is or is to be” in section 106BA(13) are sufficient to make it clear that the section has retrospective force.

The judge recognised that section 106BA “is an unusual provision” and acknowledged that he had “not found it easy” to decide whether to construe the section as having retrospective effect. Ultimately, he decided that the section applies where the obligation has already fallen due, because that is clear from the words ‘is or is to be provided’ in subsection (13). The judge considered that this wording is sufficiently clear to take away accrued rights vested in the Council. In addition, he held that the definition of ‘affordable housing requirement’ in section 106BA(13) covers the situation where the developer is obliged to pay a sum in lieu of providing affordable housing. Thus, the Council is required to discharge or modify the obligation if the conditions of section 106BA are satisfied.

TOL has one ground of appeal: the judge wrongly interpreted the wording of what I have termed Part 3(b) of the Agreement and substituted another test for that which the parties themselves chose.

The Council has one ground of appeal: the judge erred in finding that the provisions in sections 106BA and 106BC of the 1990 Act applied to accrued rights to recover commuted sums under the Agreement.

The essence of TOL’s appeal is that the judge did not interpret the words of the Agreement, rather he substituted his own test which was not that which the parties chose or intended. TOL submit that the judge should have concluded that Part 3(b) was inapplicable and that nothing was payable to the Council. In any event, TOL submit that the judge did not hold that the Proval calculation was an equivalent grant calculation nor could he have done so because the Proval method is different from that specifically agreed by the parties. Even if it could be argued that Proval was equivalent to the SHG calculation before 2006, it was not so at the time the affordable housing units were sold between 2007 and 2014.

In order to distinguish Arnold v Britton [2015] UKSC 36 (see below) on the facts of this case, TOL submitted that:

The Council submits that the Agreement makes clear provision for the payment of a commuted sum which they submit is the primary obligation consistent with the underlying bargain of the contract. The other provisions are concerned with the calculation of the sum. The court should assist the parties to settle matters so as to preserve rather than to destroy the bargain.

The Council invites this court to uphold the judge’s approach and to conclude that it did not extend beyond established principle for the following reasons:

In addition, the Council does not accept that the Judge was correct to find that if Part 3(b) “is inapplicable, then Mr Brown is correct that nothing is payable to the Council”. The Council submits that if the words following “for the avoidance of doubt” cannot be applied, then the bargain should still be upheld and a commuted sum identified.

This issue turns on the balance between giving effect to the intention of the parties and the language of the contract. It is convenient to set out the principles which both parties rely upon from the authorities that were cited to us. In Arnold v Britton [2015] UKSC 36 Lord Neuberger sets out six principles, the first and sixth of which are relied upon by the parties:

It is obvious that the language of the Agreement creates the problem that is to be solved. The Agreement did not only deal with the eventuality that SHG would be abolished. The Agreement expressly allowed for an equivalent method of calculation but did not contemplate that the system of funding for registered social landlords would fundamentally change. What then should be done? I have come to the conclusion that the judge’s interpretation of the Agreement was correct for the reasons which he gave and for the reasons which follow.

The intention of the parties was that a commuted sum should be paid. This is a conclusion that is made clear at [61(i)] to [61(iii)] of the judgment and it is not disputed by TOL. The intention was translated by the parties into the primary obligation to make a payment of a commuted sum which is set out in paragraphs 6.12.1 and 7.8.3 of the Agreement. The Council says that planning permission would not have been granted without the commitment of TOL’s predecessor to pay a commuted sum. In addition, the sum of money was originally capable of quantification; it is only subsequent events that led to the uncertainty. The uncertainty relates only to quantification not the principle of payment.

It would defeat the underlying purpose of the Agreement if the clause were unenforceable due to lack of certainty. The consequence would be that TOL would receive the benefit of planning permission without providing affordable housing or a commuted sum. In simple terms, that was not the bargain.

The sixth factor identified by Lord Neuberger in Arnold v Britton provides for a situation like this: an event has occurred which was not contemplated by the parties, namely the abolition of SHG. The question is whether in that circumstance the intention of the parties is clear. If so, the court should give effect to that intention. As I have explained above, I think the intention of the parties is very clear: TOL should pay a sum of money to the Council if they do not provide affordable housing. In coming to that conclusion I have considered the careful guidance given in Arnold v Britton in the context of the guidance given in Rainy Sky SA v Kookmin Bank [2011] 1 WLR 2900 with the considerable assistance of the overview provided by Lord Hodge in Wood v Capita Insurance Services Ltd [2017] AC 1173 at [8] to [14].

Since the hearing before us the decision of the Court of Appeal in Openworld Ltd v Forte [2018] EWCA Civ 783 has been published. Paragraphs [24] to [30] of the judgment of Simon LJ (with whom Arden and Newey LJJ agreed) describe a basis for construction that is analogous to the one that I suggest is correct in this case. If I needed further persuasion, Openworld provides clear support for the construction proposed.

If I am right then the quantification of that sum should be that which is equivalent to the amount of money which would have been provided had the SHG remained in being. Although this is a departure from the literal words of the contract, this is the only sensible solution to the problem posed by the abolition of the SHG on which the clause is premised. The clause provides that the developer should pay enough money so that the Council can provide equivalent affordable housing: the best the court can do is work out a roughly equivalent figure for that sum.

I have come to the clear conclusion that the judge identified a calculation which provided a roughly equivalent sum:

In summary, I think the Agreement should be read as requiring payment of a commuted sum which should be equivalent to the amount of SHG that would have been payable. Contrary to what TOL submits, the court is not using business common sense retrospectively to allow the Council to renege on a bad bargain; but rather there was a bargain to which the parties should be held. The decision of the judge gives effect to the intention of the parties and I would uphold his decision and dismiss TOL’s appeal.

The Council submit “that a statute will only be construed as having retrospective effect if it is plain that it was intended to have that effect or, to put it another way, that such a construction is unavoidable”: Lawrence v Financial Services Commission of Jamaica [2009] UKPC 49 per Lord Clarke at [28]. Accordingly, they submit that the judge was wrong to find that any prospective success on the section 106BC appeal could affect the existing liability of TOL to pay the sums due. They submit that it is not part of the statutory regime under sections 106BA and 106BC that accrued rights to recover commuted sums falling due under a section 106 agreement should be affected by the success of an application or appeal under these provisions. The Council submits that the judge’s reasoning is flawed. It leads to the consequence, which the parties cannot have intended, that TOL may be able to take advantage of the Agreement to permit the sale of the affordable housing units on the open market, but not pay for doing so.

Their reasoning is as follows:

In the alternative, the Council submits that if section 106BA has the effect of altering accrued rights, a later decision pursuant to section 106BA cannot alter the obligation to pay sums which fell due before section 106BA came into force. Only two of the 13 obligations to pay commuted sums occurred after that date (25 April 2013). To construe the statutory provisions to have such a profound retrospective effect would cause serious unfairness to the Council.

TOL submits that there is nothing in the language of section 106BA which limits the procedure to cases where the development has not commenced or has stalled and that if an application under section 106BA succeeds, the result is that the section 106 agreement is enforceable as modified from the date of the modification. The language of section 106BA(13), and the phrase “is or is to be”, in particular, makes it clear that section 106BA can be used where the obligation to make affordable housing available has already been triggered.

Furthermore, the judge’s conclusion is entirely consistent with the underlying rationale behind sections 106BA and 106BC, namely the desire to release constraints upon the delivery of housing. Larger housing schemes are frequently subject to staged obligations, and the developer may reach the first of the triggers and be unable to continue the development. The judge’s conclusion is also said to reflect the common understanding of the way in which sections 106BA and 106BC were intended to operate as to which TOL provided examples which included a Secretary of State’s Appeal Decision, the decision in Medway Council v. Secretary of State for Communities and Local Government [2016] EWHC 644 (Admin) (“Medway”) and the Council’s own treatment of TOL’s section 106BA application in this case over a period of some eight months.

TOL submits that the fact that s.106BA(5)(c) empowers the Secretary of State to “determine that the planning obligation is to be modified to remove the requirement” says nothing about whether the modification is to be retrospective and section 106BA(13) is broad enough to cover cases where the housing is to be provided by a local planning authority using commuted sums, because of the closing words of the subsection, “and it is immaterial for this purpose where or by whom the housing is or is to be provided”.

In response to the Council’s submissions, TOL notes that the DCLG guidance does not enjoy any particular legal status and it is for the courts to interpret legislation. It also suggests that the Council’s argument about section 106A supports TOL’s case in the sense that the Council appears to accept that section 106A can have retrospective effect and it does not point to a material difference between the wording of section 106A and section 106BA. Given that section 106BA is the obvious route for these challenges, because it was specifically designed for cases involving affordable housing requirements, it would produce a procedural minefield if section 106A was in fact the appropriate route.

The first, and until this case, only case to deal with sections 106BA and 106BC was Medway. The case was decided by the late Mr Justice Gilbart. In Medway, the council was seeking judicial review of a decision of the Secretary of State under section 106BC. The fourth issue in that case is the first question in this appeal. Sadly, given that his guidance might well have been persuasive, Gilbart J held that it was unnecessary to determine the issue although he did remark that the Act was silent on the point.

I must accordingly return to first principles. The general principle is that legislation is presumed not to be intended to have a retrospective effect unless the contrary intention appears: Bennion on Statutory Interpretation (6^th Ed), section 97. Lord Nicholls in Wilson v First County Trust Ltd (No 2) [2004] 1 AC 816 at [18] and [19] refers to this, while noting that such principles are vague and imprecise and cannot be dependent on when a case is heard by a court. Lord Nicholls thus sought the underlying rationale and gained assistance from the judgment of Staughton LJ in Secretary of State for Social Security v Tunnicliffe [1991] 2 All ER 712 at 724:

Lord Nicholls then formulated the approach that is to be followed in this way: “the appropriate approach is to identify the intention of Parliament in respect of the relevant statutory provision”: (see [19]). The intention of Parliament will of course be a unitary one but the exercise will involve all admissible aids to construction as well as the language used.

Sections 106BA and 106BC are complicated provisions and it is difficult to identify from their language the precise intention of Parliament as respects the issue before this court. The following points can be made about the intention of Parliament from the language used:

The relevant policy guidance may be examined to help understand the meaning of the legislation but only within strict parameters given that interpretation is not for the Executive. Those parameters are generally held to be the general purpose, giving context to the legality of a public authority’s conduct rather than the precise meaning of the legislative provision (see, for example, R (Risk Management) v Brent LBC [2010] PTSR 349 at [109] to [11] per Pill LJ and [227] per Moore-Bick LJ). The relevant guidance is the DCLG Guidance: Section 106 affordable housing requirements, to which a local planning authority and the Secretary of State must have regard in making a determination under sections 106BA or 106CA: see section 106BA(8)(a). It is at least arguable that guidance which a local authority must have regard to in making a determination will weigh more heavily with a court charged with interpreting a legislative provision.

The purpose of the provisions in sections106BA and 106BC is identified as being to address section 106 agreements which are “an obstacle to house building”, and focuses upon “stalled schemes” (paragraph 2). The Council submits that this guidance implies that the statutory purpose would be cut across if accrued rights were to be affected. TOL submits that the altering of accrued rights is consistent with this guidance. In fact, affordable housing obligations can arise part way through a development (as they did in Medway). It would be consistent with the purpose as expressed in the DCLG Guidance if such an obligation could be discharged or modified in order for the development to continue. I prefer TOL’s submission in this regard.

There is, however, a more significant argument concerning the purpose and context of the legislative provisions that informs the solution. The statutory scheme provides a purpose for the modification and discharge provisions in section 106BA. At section 106BA(3)(a) the purpose is set out with clarity:

“if the affordable housing requirement means that the development is not economically viable, the authority must deal with the application in accordance with subsection (5) so that the development becomes economically viable”

The way in which sections 106BA and 106BC work so as to achieve the purpose is that the developer makes an application to the council and then to the Secretary of State. The developer must submit evidence that the development has become ‘not economically viable due to the affordable housing requirement’. The council and the Secretary of State will then determine whether the development is economically viable on the basis of the evidence submitted, and will determine which of the actions in section 106BA(5) are to follow if it is not viable.

There is thus a new public interest identified by Parliament in the legislative provisions which amended the 1990 Act (by section 7 of the Growth and Infrastructure Act 2013) which outweighs the pre-existing public interest in the provision of affordable housing. In introducing sections 106BA and 106BC Parliament interfered with and removed the right of local authorities to enforce or insist upon section 106 affordable housing agreements even in the circumstance that the local authority would not have granted planning permission without the affordable housing agreement. Section 106BA(3) is in terms an interference with pre-existing rights: it applies to agreements entered into before and after the 2013 Act amendments and it accordingly has retrospective effect. Economic non-viability may occur before or after liability is triggered with the consequence that the concept cannot be taken not to apply to parts of a development already completed.

The pre-condition of economic non-viability mitigates the risk of unfairness to the Council. The Council’s accrued rights will only be affected if the Secretary of State deems the development to be not economically viable. The revised legislative purpose of facilitating development where affordable housing requirements have become too onerous is fulfilled and the effect on the Council is a necessary result of that.

The Council submits that section 106A is the legislative provision which TOL can avail itself of to alter accrued rights. The terms of sections 106A and 106BA are similar as regards the modification of obligations and there is no rational explanation for the conclusion that Parliament was content to authorise a retrospective application under section 106A but not under section 106BA. Either both sections can have retrospective effect or neither. Furthermore, section 106BA is clearly the more appropriate section to be used for the modification of affordable housing requirements given that it was designed specifically for developments involving affordable housing. I do not think that the existence of section 106A provides support for the Council’s appeal.

In my judgment, sections 106BA and 106BC do affect accrued rights. The Council or the Secretary of State is required to discharge or modify the obligation if the conditions of section 106BA are satisfied. Although the statute is silent on the point, it also does not exclude accrued rights. The policy behind the statute taken together with the practical effect of sections 106BA and 106BC indicate that the legislative provisions have retrospective effect. Although Parliament is presumed not to have legislated to alter accrued rights, I think that the contrary intention is established.

The Council submits that if the court finds that sections 106BA and 106BC can alter accrued rights, this should not extend beyond the commencement of the legislative provisions. I do not agree. There is nothing limiting the operative provisions to this period of time, and there is no difference between an obligation accruing before the commencement of the provisions and an obligation accruing after. In either case, the contract may have been entered into before the provisions came into effect and thus without knowing of the effect of the same. I consider that sections 106BA and 106BC do affect accrued rights regardless of when they accrued.

I would dismiss the Council’s appeal.

Accordingly, for the reasons I have given I would dismiss both appeals.

I agree.

I also agree.

A planning obligation may not be modified or discharged except—

by agreement between the appropriate authority (see subsection (11)) and the person or persons against whom the obligation is enforceable; or

in accordance with —

this section and section 106B, or

sections 106BA and 106BC.

An agreement falling within subsection (1)(a) shall not be entered into except by an instrument executed as a deed.

A person against whom a planning obligation is enforceable may, at any time after the expiry of the relevant period, apply to the appropriate authority for the obligation—

to have effect subject to such modifications as may be specified in the application; or

to be discharged.

In subsection (3) “the relevant period” means —

such period as may be prescribed; or

if no period is prescribed, the period of five years beginning with the date on which the obligation is entered into.

An application under subsection (3) for the modification of a planning obligation may not specify a modification imposing an obligation on any other person against whom the obligation is enforceable.

Where an application is made to an authority under subsection (3), the authority may determine—

that the planning obligation shall continue to have effect without modification;

if the obligation no longer serves a useful purpose, that it shall be discharged; or

if the obligation continues to serve a useful purpose, but would serve that purpose equally well if it had effect subject to the modifications specified in the application, that it shall have effect subject to those modifications.

The authority shall give notice of their determination to the applicant within such period as may be prescribed.

Where an authority determine under this section that a planning obligation shall have effect subject to modifications specified in the application, the obligation as modified shall be enforceable as if it had been entered into on the date on which notice of the determination was given to the applicant.

Regulations may make provision with respect to—

the form and content of applications under subsection (3);

the publication of notices of such applications;

the procedures for considering any representations made with respect to such applications; and

the notices to be given to applicants of determinations under subsection (6).

Section 84 of the Law of Property Act 1925 (power to discharge or modify restrictive covenants affecting land) does not apply to a planning obligation.

In this section “the appropriate authority” means–

the Mayor of London, in the case of any planning obligation enforceable by him;

in the case of any other planning obligation, the local planning authority by whom it is enforceable.

The Mayor of London must consult the local planning authority before exercising any function under this section.”

Where an authority (other than the Secretary of State) —

fail to give notice as mentioned in section 106A(7); or

determine under section 106A that a planning obligation shall continue to have effect without modification,

For the purposes of an appeal under subsection (1)(a), it shall be assumed that the authority have determined that the planning obligation shall continue to have effect without modification.

An appeal under this section shall be made by notice served within such period and in such manner as may be prescribed.

Subsections (6) to (9) of section 106A apply in relation to appeals to the Secretary of State under this section as they apply in relation to applications to authorities under that section.

Before determining the appeal the Secretary of State shall, if either the applicant or the authority so wish, give each of them an opportunity of appearing before and being heard by a person appointed by the Secretary of State for the purpose.

The determination of an appeal by the Secretary of State under this section shall be final.

Schedule 6 applies to appeals under this section.

In the application of Schedule 6 to an appeal under this section in a case where the authority mentioned in subsection (1) is the Mayor of London, references in that Schedule to the local planning authority are references to the Mayor of London.”

This section applies in relation to an English planning obligation that contains an affordable housing requirement.

A person against whom the affordable housing requirement is enforceable may apply to the appropriate authority—

for the requirement to have effect subject to modifications,

for the requirement to be replaced with a different affordable housing requirement,

for the requirement to be removed from the planning obligation, or

in a case where the planning obligation consists solely of one or more affordable housing requirements, for the planning obligation to be discharged.

Where an application is made to an authority under subsection (2) and is the first such application in relation to the planning obligation—

if the affordable housing requirement means that the development is not economically viable, the authority must deal with the application in accordance with subsection (5) so that the development becomes economically viable, or

if paragraph (a) does not apply, the authority must determine that the affordable housing requirement is to continue to have effect without modification or replacement.

Where an application is made to an authority under subsection (2) and is the second or a subsequent such application in relation to the planning obligation, the authority may—

deal with the application in accordance with subsection (5), or

determine that the affordable housing requirement is to continue to have effect without modification or replacement.

The authority may—

determine that the requirement is to have effect subject to modifications,

determine that the requirement is to be replaced with a different affordable housing requirement,

determine that the planning obligation is to be modified to remove the requirement, or

where the planning obligation consists solely of one or more affordable housing requirements, determine that the planning obligation is to be discharged.

A determination under subsection (5)(a), (b) or (c)—

may provide for the planning obligation to be modified in accordance with the application or in some other way,

may not have the effect that the obligation as modified is more onerous in its application to the applicant than in its unmodified form, and

may not have the effect that an obligation is imposed on a person other than the applicant or that the obligation as modified is more onerous in its application to such a person than in its unmodified form.

Subsection (6)(b) does not apply to a determination in response to the second or a subsequent application under this section in relation to the planning obligation; but such a determination may not have the effect that the development becomes economically unviable.

In making a determination under this section the authority must have regard to—

guidance issued by the Secretary of State…

Where an authority determine under this section that a planning obligation is to have effect subject to modifications, the obligation as modified is to be enforceable as if it had been entered into on the date on which notice of the determination was given to the applicant.

In this section and section 106BC—

identifies a local planning authority in England as an authority by whom the obligation is enforceable, and

does not identify a local planning authority in Wales as such an authority.

Where an authority other than the Secretary of State—

fail to give notice as mentioned in section 106BA(9),

determine under section 106BA that a planning obligation is to continue to have effect without modification, or

determine under that section that a planning obligation is to be modified otherwise than in accordance with an application under that section,

Subsections (3) to (8) , (10) and (11) of section 106BA apply in relation to an appeal under this section as they apply in relation to an application to an authority under that section, subject to subsections (7) to (15) below.

References to the affordable housing requirement or the planning obligation are to the requirement or obligation as it stood immediately before the application under section 106BA to which the appeal relates.

References to the first, the second or a subsequent application in relation to a planning obligation are to an appeal under this section against a determination on the first, the second or a subsequent application in relation to the obligation (whether or not it is the first such appeal).

Section 106BA(5)(d) (discharge of affordable housing requirement) does not apply in relation to an appeal under this section.

Subsection (11) applies if, on an appeal under this section, the Secretary of State—

does not uphold the determination under section 106BA to which the appeal relates (if such a determination has been made), and

determines that the planning obligation is to be modified in accordance with section 106BA(5)(a), (b) or (c).

The Secretary of State must also determine that the planning obligation is to be modified so that it provides that, if the development has not been completed before the end of the relevant period, the obligation is treated as containing the affordable housing requirement or requirements it contained immediately before the first application under section 106BA in relation to the obligation, subject to the modifications within subsection (12).

Those modifications are—

the modifications necessary to ensure that, if the development has been commenced before the end of the relevant period, the requirement or requirements apply only in relation to the part of the development that is not commenced before the end of that period, and

such other modifications as the Secretary of State considers necessary or expedient to ensure the effectiveness of the requirement or requirements at the end of that period.

In subsections (11) and (12) “relevant period” means the period of three years beginning with the date when the applicant is notified of the determination on the appeal.

Section 106BA and this section apply in relation to a planning obligation containing a provision within subsection (11) as if—

the provision were an affordable housing requirement, and

a person against whom the obligation is enforceable were a person against whom that requirement is enforceable.

If subsection (11) applies on an appeal relating to a planning obligation that already contains a provision within that subsection—

the existing provision within subsection (11) ceases to have effect, but

that subsection applies again to the obligation.

The determination of an appeal by the Secretary of State under this section is to be final.

Sections 106BA-BC TCPA 1990 were inserted into the 1990 Act by s 7(1) Growth and Infrastructure Act 2013 with effect from 25 April 2013. Section 7 GIA 2013 went on to provide:

The amendments made by this section and that Schedule apply in relation to planning obligations within the meaning of section 106 of the Town and Country Planning Act 1990 entered into before (as well as after) the coming into force of this section.

Sections 106BA, 106BB and 106BC of the Town and Country Planning Act 1990, and subsection (5) of this section, are repealed at the end of 30 April 2016.

The Secretary of State may by order amend subsection (4) by substituting a later date for the date for the time being specified in that subsection.

The Secretary of State may by order make transitional or transitory provision or savings relating to any of the repeals made by subsection (4).”
