Well, in answer to your question, which I was getting to, it's clear in the bill that the head of the agency may conduct an investigation.
The head of the agency would determine whether or not an investigation is worthy based on the evidence provided by the member of Parliament. It's quite clear that, given the definition in the bill of what partisan activity is, and given the power of the head of the agency to conduct an investigation based on the evidence before him or her, an investigation could or could not be conducted. It's as simple as that.
