The Supreme Court on Tuesday considered a Republican attorney general’s bid to defend a restrictive Kentucky abortion law, with some liberal justices sounding skeptical that a lower court was right to reject his request to intervene.

The case is not the only abortion-related battle that the court, stacked 6-3 with conservative justices, is set to consider this term. The court already waded into the polarizing issue when it voted 5-4 not to block a Texas law banning most abortions after as early as six weeks of pregnancy. And the justices will hear arguments Dec. 1 in a pivotal case challenging the right to an abortion before fetal viability established by Roe v. Wade.
