Protesters blocked candidate registrations in dozens of electoral districts recently, which means the Supreme Court could rule candidates in the 28 constituencies were improperly registered, the Wall Street Journal reported.
Protesters blockaded the registrations in an attempt to delay the vote and the reopening of Parliament. The Feb. 2 vote would be voided if fewer than 95 percent of seats in the lower house are filled, the newspaper said. As of Wednesday's registration deadline, 94 percent of the 500 seats in the lower house were registered.
Prime Minister Yingluck Shinawatra dissolved Parliament Dec. 9 after two months of demonstrations accusing former Prime Minister Thaksin Shinawatra of running the country through his sister. Yingluck said reforms would come after the elections, but protesters want the change instituted before the voting.
