What did the court decide in Pugh v. Holmes?
Answered for: Pennsylvania
we find that the doctrine of caveat emptor has outlived its usefulness and must be abolished, and that, in order to keep in step with the realities of modern day leasing, it is appropriate to adopt an implied warranty of habitability in residential leases
Pennsylvania's Supreme Court abolished caveat emptor for residential leases and adopted the implied warranty of habitability. The sentence above is the court in its own words.
This answer is true in Pennsylvania and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for Pennsylvania.
