The DCA accords immunity to US militaries protecting them from any juridical pursuits against them in this country. However, in cases of particular importance to Bulgarian authorities that waiver of primary Bulgarian criminal jurisdiction may be recalled (Paragraph 1, Article X of the Defense Cooperation Agreement). The U.S. Embassy has said that the agreement builds on the NATO Status of Forces Agreement (SOFA). Bulgaria retains the right to exercise its jurisdiction when it is in Bulgaria's interest. In other cases, the United States will exercise jurisdiction over U.S. military and civilian personnel.
