DEWAN Negara president Wan Junaidi Jaafar said that any effort by political parties to amend their constitution, to prevent their members, particularly MPs, from switching allegiance to the opposing side, may be subject to legal challenges.

He said that such amendments require approval from the Registrar of Societies (RoS). Additionally, he suggested that the government should consider amending the Anti-Party Hopping Act to address existing loopholes.
