Yushchenko signed a decree late Monday abolishing the Kiev District Court, replacing it with two administrative courts, after the court ruled in favor of a lawsuit filed by the Yulia Tymoshenko Bloc Saturday against the president and the Central Election Commission (CEC) and overturned the presidential decree to dissolve parliament.
The secretariat of President Yushchenko filed an appeal later Saturday against the ruling.
The Kiev Prosecutor's Office has launched a criminal case against the Kiev judge who ruled to suspend the decree on allegations of knowingly passing an unlawful ruling.
The country's pro-Western ruling coalition collapsed on September 3 when the pro-presidential Our Ukraine withdrew from the alliance after Tymoshenko's bloc joined with the opposition Party of Regions, led by Russia-friendly Viktor Yanukovych, to approve legislation substantially cutting presidential powers. Yushchenko called the move a "constitutional coup."
Under the Ukrainian constitution, the president can dissolve parliament and call early elections if no majority coalition is formed within 30 days.
The coalition was officially dissolved on September 16 and, according to the Ukrainian law, elections must take place 60 days after parliament has been dissolved.
