Those who spoke out about the abuses of their side in the conflict were seen as traitors to their community, and therefore, only a few became witnesses in war crime trials.  The international institutions ICTY, UNMIK and EULEX, and national courts in Serbia and Kosovo, have all had problems in ensuring safety for testifying protected witnesses.  According to observers, one of the main reasons that the Kosovo Relocated Specialist Judicial Institution will partly operate outside Kosovo is the past failures of the international institutions to protect witnesses.  According to Carla Del Ponte, the former ICTY prosecutor, "the investigation of the Kosovo Liberation Army fighters appeared to be the most frustrating of all the investigations done by the ICTY", and stated "witnesses were so afraid and intimidated that they even feared to talk about the KLA presence in some areas, not to mention actual crimes".  She further stated that "I am convinced that UNMIK and even KFOR officers were afraid for their lives and the lives of their missions’ members.  I think some of the ICTY judges were afraid that they would become a target for the Albanians" and believes that witness intimidation seriously affected the acquitting verdicts against KLA officials Fatmir Limaj and Ramush Haradinaj.  Numerous witnesses did change their testimonies during trials, while others were killed or mysteriously disappeared.  Avni Zogiani, leader of an anti-corruption nongovernmental organization in Kosovo, said "Intimidation and even killings of witnesses are nothing new or shocking in Kosovo".  EULEX prosecutor Charles Hardaway said that "Witness intimidation, not only in war crimes but in other cases too, is happening from people with high competencies in government who are powerful".  According to Belgian author Jelle Janssens, it was reported that judges and prosecutors became terrified at the mention of high-ranking KLA officers or politicians in case files.  Del Ponte asserts that there were serious abuses of witnesses in Kosovo local criminal proceedings, and also alleged that UNMIK leaked sensitive information about witnesses to defendants, which UNMIK denied but later admitted that it had stopped some investigations into high-level perpetrators due to political reasons.  The Humanitarian Law Center concluded that a large number of acquittances were due to witnesses changing their stories, suspecting intimidation. <SEP> The Reichskammergericht (] , "Imperial Chamber Court"; Latin: "Iudicium imperii" ) was one of two highest judicial institutions in the Holy Roman Empire, the other one being the Aulic Council in Vienna.  It was founded in 1495 by the Imperial Diet in Worms.  All legal proceedings in the Holy Roman Empire could be brought to the Imperial Chamber Court, except if the ruler of the territory had a so-called "privilegium de non appellando", in which case the highest judicial institution was found by the ruler of that territory.  Another exception was criminal law.  The Imperial Chamber Court could only intervene in criminal cases if basic procedural rules had been violated.
