The court said in its ruling today that Mrs Salakcharid Tiyapairat, now the president of Chiang Rai provincial council, provided false information during the registration of candidacy in the provincial assembly election in Chiang Rai.
It then handed down five-year imprisonment verdict on her.
But with regard to her past good deeds, the court commuted the sentence by half to two years and six months in prison instead.
However, she was given a two-year probation for the prison term.
She was also banned from running in election and engaged in political activities for 10 years, and a fine of 50,000 baht.
Earlier in 2009, Yongyut was also sentenced to serve two months in prison and a five-year ban on politics for covering up and failing to declare his asset to the National Anti Corruption Commission. However, his two-month prison term was commuted to one year probation instead.
