Srisuwan said he would ask the Constitutional Court to rule on the government’s decision to invoke Article 44 to switch land managed by the Agricultural Land Reform Office (ALRO) to use in mining and the generation of energy.

Using the article to override existing legislation “violates” Prime Minister Prayut Chan-o-cha’s “promise”, since he has urged everyone to obey the law, Srisuwan said in a statement issued on Wednesday.

He said its use to convert farmland would serve the interests of businesspeople rather than the common good.

The Cabinet on Tuesday endorsed the use of Article 44 to allow petroleum exploration, renewable energy generation and mining on ALRO land.

More than 3,600 rai (576 hectares) under ALRO control could be used for the production of fuel, windmills to generate electricity, and mining by companies with state contracts or concessions, Government Spokesman Lt-General Sansern Kaewkamnerd said.

Civic groups had opposed the change in land use, noting that the land was earmarked for struggling farmers, not private businesses, and as such was protected by a Supreme Administrative Court ruling.
