My Lords, I support each of the three amendments in this group. I was going to say that the amendment from the noble Lord, Lord Moylan, concerning compensation, was so articulate that it really needed no reinforcement, but I was not expecting the fine history lesson just now, which has reinforced it with great skill and humour. The noble Baroness, Lady Deech, explained that she taught property law for many years. I studied property law for many years, and I am sure that, if I had studied under her—which would of course not have been appropriate at all in age terms—it would not have taken me so many years.
The expropriation is bad enough, but to add the retrospective characteristic in this legislation is shameful. My principal interest in contributing is the 80-year rule referred to by the noble Lord, Lord Howard of Rising, because that is a very sensible, intelligent compromise to the sledgehammer of absolute abolition of marriage value and hope value in the calculation being entirely reserved to the lessees. Many of the highest-value elements of this paragraph are, indeed, in central London and the south-east, and many are non-resident.
This clause would save the Treasury billions, in addition to earning it some billions, which we heard referred to by the noble Lord. There is logic to the 80 years proposed in his clause. That is the threshold below which mortgagees such as banks and building societies are very reluctant to lend on property. Lessees therefore have no choice but to negotiate an extension if they want to use borrowed money—and, of course, nearly all do. The 80-year rule is a compromise between the very long leases and those moving into the unmortgageable zone. It makes a great deal of sense to cut the pack in this way because it excludes those freeholders of over 80 years but encapsulates the value of the expiring leases. It should be supported.
