Election Commissioner Somchai Juengprasert said the banned former executives may not be doubly penalised, but the candidates and political parties might have to suffer the result.

If the parties or candidates do not stop the former executives from helping them in the campaigns, others might file complaints that the parties are in favour of breaking the law, he said.

Candidates might have their voting rights revoked and the parties might have to face to dissolution if they allowed conduct that led to an unfair election, he said.
