* Law passed in February hurt Uganda's relations with West
* Court threw it out on a technicality last week
* Lawmaker says parliament could vote it back in next week

KAMPALA, Aug 6 (Reuters) - Uganda's parliament will try to re-introduce an anti-homosexuality law that was thrown out by a court, a lawmaker leading the effort said on Wednesday, a move that could once again damage relations with the West.
Last week, the east African country's constitutional court nullified the law, signed by President Yoweri Museveni in February, on a technicality, saying it had been passed by parliament without quorum.
That ruling - two days before the president flew to Washington for a U.S.-Africa summit - appeared to have handed Museveni a way out of a dilemma by striking down a law that he had backed enthusiastically but which was condemned by Western countries and threatened vital aid and investment.
It was not immediately clear whether Museveni would support the bill a second time, if passed by parliament again.
"We're mobilising members to pledge their support for re-introduction of this bill when the House comes back from recess (in about two weeks' time)," Abdu Latif Ssebaggala, told Reuters.
Ssebaggala said he had started collecting signatures on Tuesday of members of parliament in favour of re-introducing the bill and that he expected to have over 200 - in a house of 383 members - by the end of Wednesday.
Homosexuality is taboo in much of Africa and is illegal in 37 countries there. But the punishments in Uganda were among the harshest.
Under the Anti-Homosexuality Act, the crime of "aggravated homosexuality" - someone with HIV having gay sex or anyone having gay sex with someone considered "vulnerable", such as a disabled person - was punishable by life in jail.
The United States, Uganda's biggest donor, called the law "atrocious" and compared it to anti-Semitic laws in Nazi Germany and apartheid in South Africa. In June, Washington reduced aid, imposed visa restrictions and cancelled a military exercise with Uganda in response.
The World Bank, Sweden, Norway, Denmark and the Netherlands also suspended or redirected aid. Sweden resumed financial support to Uganda last week.
Ssebaggala said that as the law had already been debated, it could be put directly to a vote.
During the bill signing, Museveni said homosexuality was emblematic of the West's "social imperialism" in Africa. Powerful Christian groups with links to U.S. evangelical movements call homosexuality an imported Western social evil. (Editing by George Obulutsa and Robin Pomeroy)
