The bill was adopted in Senate at the end of May and will be sent to the head of state to be signed into law.
Opposition party USR announced Tuesday it would raise signatures to challenge the bill at the Constitutional Court.
Prime minister Sorin Grindeanu said Wednesday, ahead of the vote, the budgetary impact of the bill, RON76 billion, is sustainable.
On the other hand, analysts and international institutions including the IMF and European Commission have warned that recent tax cuts coupled with proposed wage raises in the public sector threaten to push Romania’s budget deficit past the EU limit of 3% of GDP.
