The decision, announced on 10 June 2026, concerns a petition filed by Ratchakhet Rojanamonthian. He asked the court to determine whether the Election Commission’s placement of barcode identifiers on ballot papers caused ballots to become invalid and violated Election Commission regulations governing House of Representatives elections issued in 2023.
The petitioner also argued that the Election Commission’s collection of political opinion data without voters’ consent breached Section 26 of the Personal Data Protection Act 2019. He claimed the actions infringed his rights and freedoms and conflicted with several constitutional provisions, including Sections 25, 26, 27, 32, 34, 50(7), and 224(1)(2).
The case formed part of a long-running dispute over the use of barcode and QR code technology on election ballots. Previous proceedings saw the Constitutional Court request additional information relating to the issue before reaching its latest decision.
The court stated that, based on the petition, supplementary submissions and supporting documents, if the petitioner believed his rights or freedoms had been violated, he could pursue remedies through other judicial channels under Section 25, paragraph three, of the Constitution.
The judges further noted that the Constitution and relevant organic laws already provide specific procedures and authorised parties for submitting such complaints. The court cited Section 47(2) of the Organic Act on Procedures of the Constitutional Court 2018 and noted that Section 46, paragraph three, requires the court to reject petitions that do not meet the prescribed criteria.
As a result, the court ruled that Ratchakhet was not entitled to submit the complaint under Section 213 of the Constitution and ordered that the petition not be accepted for consideration.
Amarin reported that the ruling leaves the Election Commission’s use of barcodes on ballot papers unchanged. It also clarifies that challenges of this nature must follow the legal procedures established under existing constitutional and statutory frameworks.
