Sodsri: Campaigning rules could not be amended

She said before an EC meeting with media professionals, who asked the commission to review the rules, which they claimed are both impractical and undemocratic - and far too strict.

The campaigning rules had been declared in the Royal Gazette, which meant they became law, Sodsri said. She challenged those who opposed the rules to ask the Constitution Tribunal to rule if they could be amended.

The EC approved campaigning rules on Thursday to oblige all political parties to follow its "road map" to make the election fair and equal. It claims the rules will reduce the influence of money politics.

The commission only allows all campaign billboards and posters to be set up in spots it designated. It also has the power to rule on the size of posters. The EC will also prescribe airtime on television and radio for all parties.

Candidates are only allowed to use cars to advertise campaign messages, but are banned from converting vehicles into a platform for making campaign speeches in front of a rally.
