the enactment of international and bilateral treaties which are generally adopted by unanimity or broad consensus, the actual percentage of laws passed using the urgent legislature procedure is 6.1% since 2009 and 9.4% since 2012. In other words, since 2012 one in every 10 laws passed by parliament was debated and enacted within 2 days. Parliament decides In most cases an absolute majority (50% plus one) is sufficient for a vote to pass provided there are at least 75 MPs present in the plenum, with the exception of certain bills for which the constitution requires for a higher threshold. These include treaties that transfer sovereignty to international bodies (at least 180 MPs) or changes to the electoral law so that it cannot be abused by the party in government (at least 200 MPs).

Voting takes place after the debate has finished with each MP expressing his preference by stating "yes", "no", or "present". In such cases, for the bill to pass, an absolute majority (50% plus one) is required provided that at least 120 MPs (two-fifths) vote in favour. Publication Once the bill is passed, it is sent to the president of the republic to promulgate and publish in the Government Gazette. The countersignature of the appropriate government minister(s) is required along with that of the minister responsible for justice.
