Opposition parties have every right to drum up public support for a rewrite of the constitution as long as they do so without stoking rebellion, which is against the law, Deputy Prime Minister Wissanu Krea-ngam said on Monday.
He was responding to a resolution by seven opposition parties to begin conducting public forums next month to educate people about the importance of redrafting the charter.
The opposition hopes to gather at least 50,000 signatures in support of this call.
The opposition's efforts will consist of two elements, campaigning for support to rewrite the charter and raising awareness and improve public understanding about the charter, he said.
The second element is a good idea as every citizen is encouraged to hold an opinion about the constitution, as it belongs to everyone and wasn't written for any particular group of people, according to Mr Wissanu.
The government has a similar plan to encourage members of the public to give their opinions on the constitution, he added.
Asked if he viewed the opposition's plans as an attempt to provoke rebellion, Mr Wissanu said the content and the wording of the planned campaign will determine that.
The opposition should beware of the risk of violating the law and choose their words carefully, he warned.
Meanwhile, Senator Somchai Sawaengkarn took to Facebook on Monday to counter Future Forward Party leader Thanathorn Juangroongruangkit's assertion that the Constitutional Court doesn't actually have the power to dissolve his party.
"That's nonsense. The Constitutional Court absolutely has the power to dissolve a political party for violating the law and a number of parties have been dissolved already," he said.
The senator also criticised the opposition parties for vowing to fight against any attempts to stage a new coup.
He said he wondered why they had taken a coup rumour spread by red-shirt leader Weng Tojirakarn so seriously.
