In criminal courts in The Netherlands, DNA-based evidence will only be admissible if the DNA tests have been performed by a laboratory with an ISO/IEC 17025 accreditation. Obviously, the consequences of mistakes in DNA-based evidence can be enormous. With accreditation, the government creates extra guarantees for the integrity of the judicial system and the interests of the Dutch citizens.
