(Adds comments from Klaus in paragraphs 9-10)

BRNO, Czech Republic, Nov 26 (Reuters) - The Czech Constitutional Court ruled on Wednesday that the EU reform treaty conforms with Czech law, removing an obstacle to its ratification in a country about to take over the EU presidency.
If approved by all European Union member states, the Lisbon Treaty will limit individual EU members' powers in some decisions, and give the union a permanent president and a more powerful foreign representative.
The ruling allows parliament to proceed with ratification, a process that had been held up by a constitutional challenge raised by the Senate, the upper house of the Czech parliament.
But it does not entirely rule out further legal challenges and does not guarantee smooth passage through both houses of parliament.
Failure to ratify the treaty so far has raised doubts in the EU about the performance of the 6-month Czech EU presidency, starting in January.
"It is good news for us and for all of Europe," Foreign Minister Karel Schwarzenberg told Reuters. "Despite the delay that occurred, all doubts raised by the Senate were dispelled, the Lisbon Treaty is not in conflict with the constitutional order, and let us be grateful for this certainty."
The treaty faces opposition from some government backbenchers, backed by President Vaclav Klaus, a eurosceptic who rejects any transfer of national powers to the EU.
Klaus made it clear the ruling was not the end of the road.
"I must say with regret that the court...did not deal with my legal arguments properly," he told reporters after the ruling. "I expect that some group of deputies or senators will raise these arguments again."
Klaus, whose signature is needed to complete ratification, said on Tuesday he would not stand in the way of the treaty if all other countries -- including Ireland -- agree to it.
This position is similar to that of Polish President Lech Kaczynski, who has said he will wait for an Irish 'yes' before inking the document.
Political analyst Tomas Lebeda did not expect a smooth and quick Czech approval even after the court decision.
"On the one hand there is the pressure of our EU presidency ... but on the other hand there are still very influential factions within (the ruling) Civic Democrats that are against the Lisbon Treaty," he said.
EYES ON CZECHS AND IRELAND
Prime Minister Mirek Topolanek, who also dislikes the treaty but has grudgingly backed it as a price worth paying for EU membership, has said ratification is unlikely to be completed before January, when the Czech EU presidency starts.
Topolanek has said some of his party's deputies may refuse to support Lisbon unless the leftist opposition backs plans to build a U.S. anti-missile defence radar in the Czech Republic.
The Czechs are the last EU country that has not put the treaty to a vote. It has been approved by 25 members, although ratification still needs to be completed by presidential signatures in Germany, where the top court is also reviewing the document, and Poland.
Ireland is the only member state that has rejected the treaty -- in a referendum earlier this year.
The Irish government is expected to tell its European partners next month how it wants to proceed. It has said it may ask the Irish people to revisit the question.
European Affairs Minister Dick Roche told national radio station Newstalk: "The decision by the Czech constitution court today is really very interesting -- it is the latest in a long series of positive decisions on the Lisbon treaty".
He said it was unlikely Irish voters could reverse their 'no' vote ahead of European Parliament elections in mid-2009. "In practical terms it is going to take a long time to satisfy all of the queries the Irish people have raised."
