Democratic League of Kosovo
War victims' groups and Pristina-based rights campaigners criticised recent attempts by MPs in Pristina to revoke a law which allows the new Kosovo Specialist Chambers to operate.
The president of the Association of Missing and Kidnapped Persons from Kosovo and Metohija, Ranko Djinovic, said that repealing the law would be an "injustice".
Kosovo citizens go to the polls on Sunday to vote for mayors and members of assemblies in the country's 38 municipalities, hoping a change in power will lead to a change in their daily lives.
The main battle is focused in the capital, Pristina, which is also the only municipality governed by the opposition Vetevendosje Movement.
