⁠Thailand’s King Maha Vajiralongkorn formally opened the new parliament on Saturday, as last month’s general election result faces court scrutiny over bar codes on the ballots that may have violated the law.

The bar codes might undermine the secrecy of the ‌ballot, said the country’s Office of the Ombudsman, which petitioned the Constitutional Court to consider the case.

Prime Minister Anutin Charnvirakul’s Bhumjaithai party won a clear victory in the February 8 election, but the ombudsman said late on Friday that there had been 21 public complaints that bar codes and QR codes on the ballots could potentially be used to ⁠identify which party or candidate a given voter had chosen.

The court annulled a 2006 ‌election on the grounds that the voting process had not been conducted in secret.

The Election Commission has said the bar codes were included for security purposes ‌and that identifying a voter would require access to the upper half of ⁠the ballots, which ⁠were securely stored.

Bhumjaithai, which won at least 191 seats in the 500-member parliament, has said it will form a ‌ruling coalition with the third-placed Pheu Thai party and several smaller groups, giving the alliance more than 290 seats and raising ‌the ‌prospect of a stable government after years of political volatility.
