The Parliamentary Group of the Greek Communist Party (KKE) raised the issue of Article 28 paragraph 2 of the Greek Constitution that describes that >> "is required a qualified majority of three fifths (ie at least 180 MPs) to ratify for the transfer of sovereign powers and property of the Greek state to third parties" . As per Article 28 , the Greek Constitution requires increased parliamentary majority of three / fifths (ie 180 positive votes) to vote the bill to ratify the new austerity measures. In case this procedure is not followed, and if this case in later stage goes to the Constitutional Court , the money given to Greece as bailout are not secured .. as the agreement maybe declared not valid by the court. and the money never payed back..
