Thailand’s Constitutional Court will rule on Monday on a challenge to the legality of the February 8 general election, after an ombudsman argued that barcodes and QR codes on ballots could compromise voter secrecy. Nearly 38 million people voted, handing Prime Minister Anutin Charnvirakul’s Bhumjaithai Party a decisive victory and enabling it to form a coalition controlling more than 290 of parliament’s 500 seats. The Election Commission says the codes were security measures and that identifying a voter would require access to ballot stubs stored separately. Analysts expect the court to dismiss the petition, but a finding that ballot secrecy was breached could annul part or all of the election. Even if the result stands, political analysts warn that the ruling could deepen public mistrust of Anutin’s government and erode the party’s legitimacy amid allegations of corruption and Senate-selection rigging, which Bhumjaithai denies.
