A law prohibited by the Constitution is, by definition, not "legally passed".
"A law prohibited by the Constitution is, by definition, not "legally passed"."
There are two houses of government here in NY State; the Senate and the Assembly. All gun laws originalted,were debated, and voted upon, within these two bodies, where the ELECTED representatives of the PEOPLE OF NEW YORK (whether you agree with them or not or like them or not) made the will of the people known.
Therefore, they are LEGALLY passed. Until the Supreme Court of the United States says otherwise, and since the Taylor Laws in particular have been in place snce the 1960's (I believe), I'd almost be certain they've been dragged in front of the SCOTUS, at one time or another, and evidentally passed Constitutional muster.
So, what part of LEGALLY PASSED did you not understand?
