The RoS informed SAINS on Friday about the rejection and the party said it planned to file an appeal.

In a statement, SAINS strongly denounced RoS’s decision to reject its application without providing “any reason whatsoever”.

Established online last year, SAINS touts itself as the country’s first science-based political party.

It believes in improving the quality of life of all Malaysians through a scientific approach to the democratic process and policies.

SAINS pro tem secretary-general Afiq Harraz said the party’s central executive body had agreed to exhaust all legal remedies in defending its right to association, as enshrined in Article 10(1)(c) of the Federal Constitution, should its appeal be rejected.

Separately, Muda vice-president Lim Wei Jiet said it was “really unacceptable” for government bodies to make decisions affecting the public without providing reasons.

“This is a basic requirement under the law and repeatedly emphasised by our apex court. It is a prerequisite to accountability and good governance,” he said on Twitter.

“I hope this matter goes to court,” added the lawyer.

Muda was the subject of a lengthy registration process, which started in September 2020 when the political party was founded. It only ended last month when it was finally registered by the RoS after it mounted three legal challenges.
