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 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 is refusing to concede defeat to his rival, opposition leader Viktor Yushchenko.
Observers say the appeals are unlikely to change the election results because Mr. Yanukovych lacks popular support and because the number of irregularities was not enough to narrow the gap between the two candidates.
Official results released Tuesday show Mr. Yushchenko won the runoff with 52 percent of the vote, to 44 percent for the prime minister.
