This is one of the things wrong with the Roberts' Court
This is how they screwed up the original Obamacare decision by trying to fix a mess created by the Democrats rather than just ruling on what they did. It is not the court's job and their attempts to do so is extra-constitutional. They are trying to compromise away the 1st amendment right to religious liberty.
The justices also called for additional briefing on alternative ways that employees of religious organizations could receive coverage for birth control without involving the organizations themselves. The new order could mean that the court is deadlocked on the case.
