[JURIST] The Greek parliament [official website] on Tuesday ratified the European constitution [official website; JURIST news archive], making it the fifth EU nation to sign off on the document. Approval was widely expected by Greece, with 268 lawmakers voting for the treaty and only 17 opposing it. Several opposition legislators called for a referendum on the treaty. Such a process is possible until today's parliamentary vote is published by the government, which often takes several weeks, but a successful referendum vote remains unlikely. The future of the historic European constitution remains in doubt, however, as French citizens appear ready to reject [JURIST report] the document in a referendum next month. AP has more.
