Priory Hall residents good cause of action
Though I am a consultant engineer myself, I took the advice. The residents of Priory Hall would likely have been given similar advice and should have taken it. If they were not given that advice they probably have a good cause of action against their solicitor. If they were given the advice and took it but their engineer/architect did not point out obvious or likely defects, they probably have a good cause of action against the engineer/architect.
If instead they relied on certification provided by the vendor’s solicitor or supervising engineer/architect and this was defective or deficient, they probably have a good cause of action against one or other or all. If they were given the advice and did not take it, ”Caveat Emptor” applies and they have a good cause of action against themselves.
