Notably, while every witness to the Commission gave evidence of frequent corporal punishment, applied contrary to the regulations and therefore criminally, no Church witness came forward to certify a single such case. Difficulties arose where complainants or the accused were involved in parallel criminal or civil cases, such as the vaccine trials performed on inmate children. With such divergent views the CICA's task has been difficult and contentious, but it has agreed with the evidence given by the complainants. Given Mr. Ahern's general apology in 1999, it would be hard to conclude otherwise.
