First, the Civilian Review and Complaints Commission, the CRCC, which is the existing body attached to the RCMP, is the one that was quite concerned that the language in their act, the RCMP Act, was imported over to Bill C-59. They're the ones who brought it up as very important.
I'm not familiar with specific examples where this was used. It's probably more in the normal civilian complaints relative to normal police behaviour, but I thought it was important enough to include just in case there was a need.
