What do you know about the Supreme Court case: Ker v. California?

Answer 1

It concerned if a search which found illegal items (in this case drugs) was illegal. It further defined what searches did not require a warrant and upheld that evidence obtained with out a warrant that required one had to be excluded.

Answer 2

I think one of the most important parts of Ker is its recognition (along with Di Re) that the lawfulness of a search is dependent upon State law--a violation of state law renders a search unreasonable as a matter of federal constitutional law. This is a point which appears to have been lost upon the California judiciary in recent years.
