When the justices take the bench for oral arguments on Wednesday, one seat will be empty: Justice Amy Coney Barrett, the junior member of the court’s conservative supermajority, has recused herself from the case, which means she will not take part in the oral arguments, deliberations or vote.

Supreme Court Justice Amy Coney Barrett gave no explanation for why she recused herself from a religious charter school case that was set to begin oral arguments Wednesday, The New York Times reported.
