Thailand's progressive Move Forward Party, which won most seats at the last election, faces a crunch court ruling Wednesday on the legality of its campaign pledge to reform the kingdom's tough royal defamation laws.
MFP upended Thailand's political order by coming first in the general election last May, but its promises to reform the military, business monopolies and lese-majeste laws spooked the kingdom's powerful conservative elite.
Leader Pita Limjaroenrat was blocked from becoming prime minister and MFP was shut out of the governing coalition.
Pita returned last week to parliament after he was cleared of breaching election laws in a case that could have seen him barred from politics.
Now the Constitutional Court is scrutinising the party's campaign promise to
reform Thailand's strict laws protecting King Maha Vajiralongkorn and his close family from insult.
The court is expected to issue a ruling around 2:00 pm (0700) on a petition arguing the MFP policy amounted to an attempt to overthrow Thailand's monarchy. The court is not expected to order the party's dissolution, but could tell it to drop its lese-majeste reform policy.
Thanathorn Juangroongruangkit, the former leader of Future Forward Party --an MFP forerunner dissolved by court order -- said lese-majeste should be up for discussion.
"The law is not a fax paper sent from God.
It's written by human hands, therefore people can amend it," Thanathorn told reporters on Wednesday.
"If the lawmakers cannot amend the laws, I think something is wrong in the country."
The yellow bath toys were an unexpected symbol of mass youth-led street protests that shook Bangkok in 2020.
Reform of the lese-majeste law, known in Thailand as 112 after the relevant
section of the criminal code, was a major theme of the demonstrations, which
featured unprecedented public criticism of the royal family.
More than 250 people have faced royal insult charges in the wake of the
protests, according to Thai Lawyers for Human Rights, a legal group that
handles many cases.
They include senior protest leaders and at least one elected MP.
