In many cases, the practice of violating constitutional rights in the evidence seeking raises the falses punishment. In Indonesia, coercive efforts to find evidence can be tested through pretrial institutions. Unfortunately, the existence of pretrial in Indonesia only test the formal truth of coercive measures and it is not yet authorized to examine the material truth. This article intends to explain the urgency and application of the exclusionary rule in various countries as well as the idea to push the regulation of exclusionary rules that allow judges to be not only examining judges but also investigating judges.
