The answer will depend on the wording of the order made by the LT, but the key point to note is that it can never be a wider group of people than were originally able to enforce the covenant. Thus, the starting point will be that a covenant can be enforced by those who originally had the benefit of the un-modified covenant, unless the LT’s modification said that the benefit was to be confined to a narrower class. What the LT cannot do, however, is extend the benefit of the covenant to a wider group that were not previously able to enforce the covenant.
