  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).
  
  Custom, namely the Dedilomeni Principle, dictates that there are always 75 MPs present in the plenum and that the government has the majority of MPs inside the plenum at all times, even if on occasion there are in reality more opposition MPs and less than a quarter of all 300 MPs present in the plenum. However, at any time the opposition may challenge the government by calling for a roll call vote provided that at least 15 MPs (one-twentieth) submit to the speaker a formal request. 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.
