The Supreme Court is likely to set up its showdown on gay marriage tomorrow

On Friday, the Supreme Court justices will be meeting to decide whether to hear a case — or multiple cases — challenging a ban on same-sex couples’ marriages.

This will be the second time the justices have considered whether to take any of the cases out of Kentucky, Michigan, Ohio, and/or Tennessee. When they did so on Jan. 9, they took no action on those cases, instead re-listing them for discussion on Friday.

This is a new practice by the court over the past year or so, re-listing cases they are considering taking once before accepting a case, called granting a writ of certiorari.

The justices did, however, deny an attempt by same-sex couples in Louisiana to have the Supreme Court hear their case before the appeals court — which heard their appeal on Jan. 9 — decided on the appeal.
