KYIV – Ousted Constitutional Court Chief Justice Oleksandr Tupytsky on March 29 challenged his dismissal by President Volodymyr Zelenskyy with the Supreme Court, a court filing shows.

Post-Soviet Ukraine’s sixth president had two days earlier revoked Mr. Tupytsky’s appointment to the court by reversing a presidential decree that his predecessor, Viktor Yanukovych, had signed on September 17, 2013.
