Supreme Court justices are expected to deliberate Friday over whether to consider overturning the court’s precedent legalizing same-sex marriage, meaning an announcement on the case’s fate could come within days—but it’s still unclear whether or not the justices will actually take up the case.

Today, the Supreme Court will meet behind closed doors to review a potential challenge that would overturn the landmark 2015 decision in Obergefell v. Hodges which legalized same-sex marriage.
