Can you cite a case where a tenant sued a landlord, for failure to provide 'quiet enjoyment' of the property?

Or you can do the legal research your law professor wants you to do.

Unfortunately, trial level cases are not reported in such a way where they can be cited and you can look up the documents. You would have to get the physical file to get the complaint. If you wanted a cite to a state Supreme Court or Court of Appeals case, you could get that but it would not have the complaint in its records, you could only get the decision from the Court.

Nope. "Quiet enjoyment" has very little to do with noise. It means that as long as you pay your rent, you won't be evicted. Now there is a concept called "constructive eviction." This happens when you cannot use part of the apartment; or when the apartment is so unlivable that no self-respecting tenant would live here. So you can move out, and not be liable for future rent. As to back rent, you have to show a breach of the warranty of habitability, the same problem as entitled you to cancel the lease going forward, only now you're reaching back and asking how much of a rebate on rent already paid will you get.

Court records are getting easier to find because many courts now are using electronic filing. However, there are none that I am aware of that are indexed for searching, excessive noise and quiet enjoyment. The decisions of cases that have been appealed are published and there have been available means for searching for many years, in print and electronically online. Appellate decision rarely reproduce the entire actual complaint filed in the case.

Unfortunately, published landlord-tenant decisions are not very common. Also even if the case is published, the actual pleadings are not "published" although they are public record. You would have to find the published opinion, determine where the lawsuit was filed and then view the file from the underlying case. Interference with quiet enjoyment is a valid cause of action, but generally it must be a specific act or inaction on the part of the landlord. You may wish to consult a real property attorney, or contract attorney in your area.
