Parliament had been due to vote on the ratification of the Council of Europe Convention on preventing and combating violence against women and domestic violence.
The so-called Istanbul Convention characterises domestic abuse and discrimination based on sexual orientation as violations of human rights.
It was adopted by the Strasbourg-based Council of Europe rights body in 2011 and has been ratified by more than 20 states.
But the former Soviet republic remains a deeply conservative country where Gay Pride parades are often either banned or met with violence from far-right thugs.

"The draft law on preventing and combatting violence will exclude references to 'gender' and 'sexual orientation'," Ukraine's parliament said on its Twitter account.
The short statement came after a high-decibel debate between lawmakers over what constituted Ukraine's moral values.
"The bill is filled with things that are unacceptable to our society," populist Radical Party member Igor Mosiychuk said.
Another parliament member said the mainly Christian Orthodox country should base its values on religious standards that condemn things like gay marriage.
Pro-Western President Petro Poroshenko -- a fierce foe of Russia whose forces are fighting a 31-month pro-Moscow eastern separatist war that has claimed nearly 10,000 lives -- has not said whether he backs the original version of the bill.
But a member of the president's party said he also opposed the Istanbul Convention in its current form.
"I agree that we must accept many European values - but certainly not the ones that violate the bases of Christianity," said Yuriy Solovey of the Petro Poroshenko Bloc party.
