There was a CA supreme court decision a while back that said that tenants who don't receive any refund within 21 days are entitled to get the entire amount back. Can someone help me find the text of that decision?
I searched Google Scholar of all California cases for the exact phrase "21 days" and each of the following words: deposit tenant

I got 6 hits. None of them were for the California Supreme Court.

Try different search criteria yourself.
