On Thursday 11 candidates from many political parties had been disqualified by the Election Commission due to the fact that they were already a member of another party or had represented their party for less than 90 days

The commission had said that four candidates were from Palang Rak Thai, two from Palang Chatthai and one each from Palang Puangchon Thai, Prachatham Thai, Seriruam Thai, Chatpatta and Ruamjai Thai.

None of them was successful in the March 24 general election so no byelections were necessary.  Their votes would not be used in the calculation of the party lists.
