DUBLIN Irish President Mary McAleese signed the European Union's Lisbon treaty, completing Ireland's ratification process two weeks after voters approved the pact in a referendum, her office said in a statement late on Thursday.
Polish President President Lech Kaczynski signed the EU reform treaty into law on Saturday, after two-thirds of Irish voters on October 2 said "Yes" to streamlining EU decision-making.
That leaves only the Czech Republic out of the 27 EU nations to ratify the treaty, with President Vaclav Klaus holding out for extra concessions before signing it into force.
McAleese's signature was a formality as the Irish constitution stipulates she must sign amendments if satisfied that it has been approved by the people in a referendum.
