According to California Government Code Section 54953.3: "A member of the public shall not be required, as a condition to attendance at a meeting of a legislative body of a local agency, to register his or her name, to provide other information, to complete a questionnaire, or otherwise to fulfill any condition precedent to his or her attendance.
If an attendance list, register, questionnaire, or other similar document is posted at or near the entrance to the room where the meeting is to be held, or is circulated to the persons present during
the meeting, it shall state clearly that the signing, registering, or completion of the document is voluntary, and that all persons may attend the meeting regardless of whether a person signs, registers, or completes the document."
So it would seem, at first glance, that the law is clearly on your side.
HOWEVER, one interesting point to make is that there may be a legal difference between what the City of Los Angeles can do to the entrance of City Hall, versus what they can do to the entrance of the City Council Chamber. I just point out that distinction, not to reinforce it, but to highlight it, for it may be of legal significance.
As for your First Amendment arguments, yes you can always make them in addition to claims concerning alleged violations of municipal laws.
If you wanted to proceed with a legal action, you would file in Los Angeles Superior Court, at first, a complaint requesting "injunctive relief," i.e., a Court order directing the "Sergeant at Arms" of the Los Angeles City Council to admit you at future meetings, according to the terms set forth in the Government Code, cited above.
The Court can also void actions of the City Council operating in violation of the law. It can also award damages and attorney fees.
I would suggest, first, exhausting one option: talk to your City Council Member's office, and ask them to review ID procedures, in light of state law.
