[JURIST] Ivan Dombrovsky, chairperson of the Constitutional Court of Ukraine [official website; JURIST news archive], resigned without elaboration Thursday as the 18-judge court continued to deliberate the constitutionality of Ukrainian President Viktor Yushchenko's April 2 decree [text; JURIST report] dissolving parliament and calling for new elections. The Constitutional Court has appointed Deputy Chair Valery Pshenichny to be the new chief justice. Pshenichny was the first judge dismissed [JURIST report] by Yushchenko in April.
In April, Ukrainian Prime Minister Yiktor Yanukovych [BBC profile] and leaders of Parliament filed a legal challenge to Yushchenko's decrees [JURIST report], seeking to block the dissolution of parliament. Yushchenko has subsequently dismissed three Constitutional Court judges for alleged oath and ethics violations [JURIST report], and appointed replacement judges without consultation [JURIST report] with either Yanukovych or the Justice Ministry.
