For such a hotly-debated topic, the law regarding bans and burdens on abortion hasn’t changed much. Any ban or undue burden on pre-viability abortions is unconstitutional per the Supreme Court’s holdings in Roe, Casey, and Gonzales. Since 1973, the bright line rule that a woman’s right to privacy trumps the state’s interest in “the potentiality of human life” is been repeatedly reaffirmed by the Supreme Court and the Circuit Courts of Appeal, despite many chances to modify or reject that rule.
Last year, Arizona passed H.B. 2036, which prohibited physicians from performing abortions on any fetus with a gestational age of twenty weeks or later, absent some medical emergency endangering the life of the mother. This was in addition to an existing law that prohibited abortions (absent medical emergency) at or after the point of viability.
