"A letter of resignation was, indeed, written, but the judges have turned it down," the source said. "Dombrovskiy continues performing his duties."
Following the presidential decree to dissolve parliament Monday, the Supreme Rada continued meeting and referred the decree to the Constitutional Court Tuesday.
Prime Minister Viktor Yanukovych said earlier Wednesday the court chairman could hand in his resignation.
"I have learned that the chairman of the Constitutional Court has been under pressure. As far as I know he will tender his resignation today," Yanukovych said.
