Ukraine's Supreme Court has rejected at least two complaints of election fraud filed by Prime Minister Viktor Yanukovych.
The court was expected to rule today (Thursday) on a total of four complaints by Mr. Yanukovych, who lost Sunday's presidential runoff vote.
Mr. Yanukovych alleges there were thousands of election violations and he is refusing to concede defeat to opposition leader Viktor Yushchenko.
International election monitors have said voting problems and irregularities were much fewer than in the previous runoff that Ukraine's supreme court annulled.
Official results released Tuesday show Mr. Yushchenko won the run-off with 52 percent of the vote, to 44 percent for the prime minister.
