The Polish parliament passed a resolution Friday calling on the president to sign the Lisbon Treaty as quickly as possible, local media reported.
The resolution calls for the president to "respect the will of both houses of parliament and end the Lisbon Treaty's ratification process as quickly as possible, and actively support its ratification in the remaining European Union member states," reported the Polish Press Agency.
The resolutions says the Lisbon Treaty will strengthen the EU and allow for more integration, reported dpa.
President Lech Kaczynski has said Poland will not "stand in the way" of ratifying the treaty, but that he will sign if it gets a "yes" vote in Ireland.
Ireland failed to pass the treaty in a referendum last year. A second Irish referendum is planned for later this year.
Kaczynski has called for respecting the Irish vote and warned against breaking EU unanimity.
