The parliament overwhelming decided to send the law to court on Monday with a vote of 50 for, 13 against and 35 abstentions.
The "Amended Law on the Nuclear Power Plant," which was passed in February, established the national energy company. The company was made to help cope with investments into the planned nuclear power plant that will replace the one at Ignalina and the planned power links with Polandand Sweden.
MP Kestutis Glaveckas, a member of the Liberal Union, said that the Constitution Courtcould try and give answers to certain questions that remained unanswered at the time when the law was being passed.
He also said, however, that the ruling would not change anything in practice.
