A state bill should be totally unnecessary. This is a constitutional right. If we accept this bill as the norm then its no longer a "right" and just a permission by the govt that can be rescinded at anytime.
The text[1] of the bill seems to affirm the sentiment that it's a constitutional right; it serves to counteract a California Supreme Court ruling:
"(e) It is the intent of the Legislature in enacting Section 1542.5
of the Penal Code to reject as a matter of California statutory law
the rule under the Fourth Amendment to the United States Constitution
announced by the California Supreme Court in People v. Diaz."
