Justice Don Willett writes for the Wall Street Journal:

Antonin Scalia’s untimely death in February has left the Supreme Court with an even number of justices: eight. Unlike tennis matches, Supreme Court decisions are tiebreaker-free, meaning the lower-court ruling stands without any high-court guidance.

Every state supreme court is odd-numbered (five, seven, or nine justices), but because of recusals, unfilled vacancies or prolonged absences, each court occasionally dips below full strength, thus raising the specter of supreme stalemate.
