Should your country’s laws take precedence over international agreements?

AI-generated summary, admin reviewed: This initiative proposed giving the national constitution priority over international agreements when they conflicted. Fundamental international rules, including the prohibitions against torture, slavery and genocide, would remain protected. Conflicting agreements would have to be renegotiated or terminated. Supporters argued that voter-approved constitutional rules should come first. Opponents warned that the change could weaken human-rights protections and make the country an unreliable international partner. Swiss voters rejected the initiative.
