Under the Leasehold Reform Act 1967, where a tenant has served a notice of tenant's claim to acquire the freehold or an extended lease, which correctly states that the valuation should be under section 9(1)(c) as the rent exceeds the applicable limit under section 1AA (meaning a marriage value will have to be taken into consideration for the premium), but the landlord has served a notice in reply to tenant's claim which mistakenly states that the property should be valued under section 9(1), (which does not take a marriage value into consideration and is more favourable to the tenant), will the landlord be bound to value the property under section 9(1)?
