Hungarian lawmakers approved a new Constitution Monday which bans same-sex marriage and includes a number of other socially conservative tenets, the AP reports:
Hungary's political opposition and human rights groups including Amnesty International say other measures are attempts to limit freedoms.
The constitution protects the life of a fetus from the moment of conception, a move seen as opening the possibility for a future ban or restrictions on abortion.
Same-sex couples may legally register their partnerships but marriage is restricted to heterosexual relationships.
A ban on discrimination does not mention age or sexual orientation, and the constitution allows lifetime prison sentences for violent crimes without the possibility of parole.
Approximately 3,000 people, including gay rights activists, reportedly attended a rally on Friday opposing the new document.
