10 Opposition by landlord to application for new tenancy.
(1) The grounds on which a landlord may oppose an application made under section 8 to the Lands Tribunal for a new tenancy are such of the following grounds as may be stated in the landlord's notice to determine under section 4, or as the case may be, in the landlord's notice under section 5(6), that is to say:—
(a) where under the current tenancy the tenant has any obligations as respects the repair and maintenance of the holding, that the tenant ought not to be granted a new tenancy in view of the state of repair of the holding, being a state resulting from the tenant's failure to comply with those obligations;
(b) that the tenant ought not to be granted a new tenancy in view of his persistent delay in paying rent which has become due;
(c) that the tenant ought not to be granted a new tenancy in view of other substantial breaches by him of his obligations under the current tenancy, or for any other reason connected with the tenant's use or management of the holding;
(d) that the landlord has offered and is willing to provide or secure the provision of alternative accommodation for the tenant, and—
(i) that the terms on which the alternative accommodation is available are reasonable having regard to the terms of the current tenancy and to all other relevant circumstances; and
(ii) that the accommodation and the time at which it will be available are suitable for the tenant's requirements (including the requirement to preserve goodwill) having regard to the nature and class of his business and to the situation and extent of, and facilities afforded by, the holding;
(e) where the current tenancy was created by the subletting of part only of the property comprised in a superior tenancy and the landlord is the owner of an estate in reversion expectant on the termination of that superior tenancy, that the aggregate of the rents reasonably obtainable on separate lettings of the holding and the remainder of that property would be substantially less than the rent reasonably obtainable on a letting of that property as a whole, that on the termination of the current tenancy the landlord requires possession of the holding for the purpose of letting or otherwise disposing of the said property as a whole, and that in view thereof the tenant ought not to be granted a new tenancy;
(f) that on the termination of the current tenancy the landlord intends—
(i) to demolish or rebuild the premises comprised in the holding or a substantial part of those premises; or
(ii) to carry out substantial works of construction on the holding or part thereof;
and that the landlord could not reasonably do so without obtaining possession of the holding;
(g) subject to subsection (3), that on the termination of the current tenancy the landlord intends that the holding will be occupied for a reasonable period for the purposes, or partly for the purposes, of a business to be carried on by him or by a company in which he has a controlling interest, or as his residence.
(2) Where the landlord opposes an application on the ground specified in subsection (1)( f) the Lands Tribunal may require the landlord to furnish evidence that planning permission required under any enactment has been granted to him in respect of the works which he intends to undertake.
(3) The landlord shall not be entitled to oppose an application on the ground specified in subsection (1)( g) if the estate of the landlord, or an estate which has merged in that estate and but for the merger would be the estate of the landlord, was purchased or created after the beginning of the period of five years which ends with the termination of the current tenancy, and at all times since the purchase or creation thereof the holding has been comprised in a tenancy or successive tenancies of the description specified in section 1(1).
(4) For the purposes of subsection (1)( g) the landlord shall be deemed to have a controlling interest in a company if he has the power to secure, by means of the holding of shares or the possession of voting power in or in relation to the company, or by virtue of any powers conferred by the articles of association or other document regulating that company, that the affairs of the company are conducted in accordance with his wishes.

11 Dismissal of application for new tenancy where landlord successfully opposes.
(1) The Lands Tribunal shall not make an order under this Part for the grant of a new tenancy where the landlord opposes an application under section 8 on grounds on which he is entitled to oppose it in accordance with section 10 and establishes any of those grounds to the satisfaction of the Lands Tribunal.
(2) Where in a case not falling within subsection (1) the landlord opposes an application for the grant of a new tenancy on one or more of the grounds specified in paragraphs ( d), ( e) and ( f) of section 10(1) but fails to establish any of those grounds to the satisfaction of the Lands Tribunal, the Lands Tribunal, if it would have been satisfied as to any of those grounds had the date of termination specified in the landlord's notice to determine or, as the case may be, the date specified in the tenant's request for a new tenancy as the date from which the new tenancy is to begin, been such later date as the Lands Tribunal may determine, being a date not more than one year later than the date so specified,—
(a) shall make a declaration to that effect, stating on which of the said grounds it would have been satisfied as aforesaid and specifying the later date determined by the Lands Tribunal as aforesaid, but shall not make an order for the grant of a new tenancy; and
(b) if, within fourteen days after the making of the declaration, the tenant so requires, shall make an order substituting that later date for the date specified in the said landlord's notice to determine or the tenant's request, and thereupon that notice or request shall have effect accordingly.

12 Powers of Lands Tribunal to grant a new tenancy on application.
(1) Where the tenant applies under section 8 to the Lands Tribunal for the grant of a new tenancy and—
(a) the landlord fails to establish to the satisfaction of the Lands Tribunal any of the grounds of opposition to the grant of a new tenancy under section 10; or
(b) the Lands Tribunal does not make a declaration under section 11(2);
the Lands Tribunal shall make an order for the grant of a new tenancy comprising such property, at such rent and on such other terms, as are provided in the succeeding provisions of this Part.
(2) Where a tenancy is continued or a new tenancy is granted under this Part in any premises, such continued or new tenancy shall for all purposes be deemed to be a graft upon the tenancy previously subsisting in those premises, and the interest of the tenant thereunder shall be subject to any rights or equities arising from its being such graft.
(3) Subsection (2) shall not operate so as to extend any liability under any guarantee or other security for the payment of rent.

(2) Where the property comprised in the current tenancy includes other property besides the holding and the landlord requires any new tenancy ordered to be granted under section 12 to be a tenancy of the whole of the property comprised in the current tenancy the Lands Tribunal shall make an order for the grant of a new tenancy of the whole of the property comprised in the current tenancy; and in any such case references in the succeeding provisions of this Part to the holding shall be construed as references to the whole of that property.
(3) Where the current tenancy includes rights enjoyed by the tenant in connection with the holding, those rights shall, unless the parties otherwise agree or the Lands Tribunal otherwise directs, be included in a tenancy ordered to be granted under section 12.

14 Duration of new tenancy.

(a) a tenancy for such period as may be agreed between the landlord and tenant; or
(b) in the absence of agreement, a tenancy for such period, not exceeding fourteen years, as may be determined by the Lands Tribunal to be reasonable in all the circumstances, and shall begin on the coming to an end of the current tenancy.
(2) Where the period for which in accordance with this Part it is agreed or determined by the Lands Tribunal that a new tenancy should be granted thereunder will extend beyond the date on which the estate of the immediate landlord will come to an end, then subject to subsection (3), the power of the Lands Tribunal under this Part to order such a grant shall include power to order the grant of a new tenancy until the expiration of that estate and, subject to the following provisions of this section, to order the grant of such a reversionary tenancy or reversionary tenancies as may be required to secure that the combined effects of those grants will be equivalent to the grant of a tenancy for that period; and the provisions of this Part shall, subject to the necessary modifications, apply to the grant of a tenancy together with one or more reversionary tenancies as they apply in relation to the grant of one new tenancy.
(3) The Lands Tribunal shall not under subsection (2) grant a reversionary tenancy unless the tenant has, within such time as may be prescribed by Lands Tribunal Rules, served notice of his application for a new tenancy on any person, other than the landlord, having a reversionary estate which would be affected by the grant of the reversionary tenancy.
(4) Any person having a reversionary estate which is likely to be affected by the grant of a reversionary tenancy (including any terms or conditions attached to such grant) may in accordance with Lands Tribunal Rules apply to the Lands Tribunal to be made a party to the proceedings and, on such application being granted, may oppose the grant of the reversionary tenancy on any grounds which appear to the Lands Tribunal to be relevant and shall be bound by the proceedings.

15 Rent under new tenancy.
(1) The rent payable under a new tenancy granted by order of the Lands Tribunal under this Part shall be such as may be agreed between the landlord and the tenant.
(2) In the absence of agreement the rent shall be such as may be determined by the Lands Tribunal to be that at which, having regard to the terms of the tenancy (other than those relating to rent), the holding might reasonably be expected to be let in the open market by a willing lessor, there being disregarded—
(a) any effect on rent of the fact that the tenant has or his predecessors in title have been in occupation of the holding;
(b) any goodwill attached to the holding by reason of the carrying on thereat of the business of the tenant (whether by him or by a predecessor of his in that business);
(c) any effect on rent of any improvement—
(i) carried out by the tenant or a predecessor in title of his; or
(ii) where the tenant or a predecessor in title of his has remained in occupation of the holding during two or more tenancies, carried out by him or that predecessor in title during a tenancy other than the current tenancy;
other than in pursuance of an obligation to the immediate landlord;
(d) in the case of a holding comprising premises licensed under the Licensing Acts (Northern Ireland), any addition to its value attributable to the licence, if it appears to the Lands Tribunal that having regard to the terms of the current tenancy and any other relevant circumstances the benefit of the licence belongs to the tenant.
1971 c.13 (NI)
(3) None of the provisions of the [ Rent (Northern Ireland) Order 1978 ] shall operate to limit or affect the amount of the rent which may be fixed by the Lands Tribunal under subsection (2).

(2) If the tenant, within fourteen days after the making of an order under this Part for the grant of a new tenancy, applies to the Lands Tribunal for the revocation of the order, the Lands Tribunal shall revoke the order; and where the order is so revoked, then, if it is so agreed between the landlord and the tenant or determined by the Lands Tribunal, the current tenancy shall continue beyond the date at which, but for this subsection, it would have come to an end, for such period as may be so agreed or determined to be necessary to afford to the landlord a reasonable opportunity for re-letting or otherwise disposing of the premises which would have been comprised in the new tenancy; and while the current tenancy continues by virtue of this subsection it shall not be a tenancy to which this Part (other than this subsection and subsection (3)) applies.
(3) Where an order is revoked under subsection (2) any provision thereof as to payment of costs shall not cease to have effect by reason only of the revocation; but the Lands Tribunal may, if it thinks fit, revoke or vary any such provision or, where no costs have been awarded in the proceedings for the revoked order, award such costs.
(4) An agreement made under this section, where the estate of the landlord is subject to a mortgage, shall be deemed to be one authorised by section 18 of the Conveyancing Act 1881 (which confers certain powers of leasing on mortgagors in possession), and subsection (13) of that section (which allows those powers to be restricted or excluded by agreement) shall not have effect in relation to such an agreement.

18 Powers of Lands Tribunal where landlord cannot be found or is under a disability.
Where, on an application under this Part for the grant of a new tenancy, the landlord or any landlord cannot be found or is under a disability or is acting in a fiduciary capacity, the Lands Tribunal may make such order as it may think proper to enable the new tenancy to be granted notwithstanding that impossibility of being found, disability or fiduciary capacity, as the case may be.

19 Compensation where order for new tenancy is precluded on certain grounds.
(1) Where on the making of an application under section 8, the Lands Tribunal is precluded (whether by subsection (1) or subsection (2) of section 11) from making an order for the grant of a new tenancy by reason of any of the grounds specified in paragraphs ( e), ( f) and ( g) of subsection (1) of section 10, and not of any grounds specified in any other paragraph of that subsection, then, subject to the provisions of this Part, the tenant shall be entitled on quitting the holding to recover from the landlord by way of compensation an amount determined in accordance with the following provisions of this section.
(2) The said amount shall be as follows, that is to say:—

(5) For the purposes of subsection (2) the question of net annual value of the holding shall be referred to the Commissioner of Valuation and shall be decided as follows:—

(b) where no such value is so shown with respect to the holding but such a value or values is or are shown with respect to premises comprised in or comprising the holding or part of it, the net annual value of the holding shall be taken to be such value as is certified by the Commissioner of Valuation to be attributable to the value or values so shown;
(c) where the net annual value of the holding cannot be ascertained in accordance with the foregoing provisions of this subsection, it shall be taken to be the value which the Commissioner of Valuation certifies would on a proper assessment be the value to be entered in the said valuation list as the net annual value of the holding.
(6) The Ministry of Finance may by regulations made subject to negative resolution prescribe the procedure in connection with references under subsection (5).
(7) In this section the reference to the termination of the current tenancy is a reference to the date of termination specified in the landlord's notice to determine under section 4, or, as the case may be, the date specified in the tenant's request for a new tenancy as the date from which the new tenancy is to begin.

(a) by him or a predecessor in title of his; or
(b) where the tenant or a predecessor in title of his has remained in occupation of the premises during two or more tenancies, by him or that predecessor in title during a tenancy other than the current tenancy;
not being a trade or other fixture which the tenant is by law entitled to remove, which at the termination of the tenancy adds to the letting value of the premises comprised therein.
(2) A tenant shall not be entitled to compensation under subsection (1) unless a claim in the prescribed form is served on his landlord within the time limited by section 31.

31 Time for the service of claims for compensation for improvements.
(1) The time for the service of a claim for compensation for improvements under section 30(2) shall be as follows, that is to say:—
(a) where a tenancy is terminated by notice served by the tenant or by the immediate landlord under and in accordance with the terms (whether express or implied) of that tenancy, or by a notice given by any person under Part I, the said time shall be a time falling within the period of three months beginning on the date on which the notice is served; but where a tenancy is terminated by a tenant's request for a new tenancy under section 5 the said time shall be a time falling within the period of three months beginning on the date on which the landlord serves notice, or (if he has not served such a notice) the latest date on which he could have served notice, under section 5(6);

(2) In determining the amount of such net addition as is mentioned in subsection (1)( a), regard shall be had to the purposes for which it is intended that the premises shall be used after the termination of the tenancy, and if it is shown that it is intended to demolish or to make structural alterations in the premises or any part thereof or to use the premises for a different purpose, regard shall be had to the effect of such demolition, alteration or change of user on the additional value attributable to the improvement, and to the length of time likely to elapse between the termination of the tenancy and the demolition, alteration or change of user.
(3) In the absence of agreement between the parties, all questions as to the right to compensation under this Part, or as to the amount thereof, shall be referred to and determined by the Lands Tribunal, and if the Lands Tribunal determines that, on account of the intention to demolish or alter or to change the user of the premises, no compensation or a reduced amount of compensation shall be paid, the Lands Tribunal may authorise a further application for compensation to be made by the tenant if effect is not given to the intention within such time as may be fixed by the Lands Tribunal.
