Poland's lower house of Parliament, Sejm, passed the bill allowing for ratification of the EU fiscal pact during a voting on Wednesday.

Out of 438 MPs participating in the vote, 282 were in favor, 155 against the bill and one abstained. The pact can now be ratified by President Bronislaw Komorowski.

The Fiscal Stability Treaty was signed in Brussels in March 2012 by 25 EU member states. The pact sets the rules of stricter discipline in national budgets in order to prevent a new debt crisis in the euro zone in the future.

The ratification of the pact by Poland means accepting its postulates but puts no additional obligations on Poland as long as the country stays outside of the euro zone.

The move was opposed by the main opposition conservative Law and Justice (PiS). The party filed for rejecting the ratification law in the second reading.

PiS leader Jarosław Kaczyński said that the fiscal pact “significantly impairs our sovereignty”.

PiS wants the pact to be looked at by Poland's Constitutional court.
