Well, the protocol was introduced before the 2019 election, along with several other measures, including the continuation of the RRM, which is critically important to protecting our democracy. I think that was a very good first step. In 2019, it appears to have done its work. Whether it was to deter foreign actors from trying to interfere...it seems to have done its work.
I cannot comment on the thresholds that were put in place. With this incident and the fact that Chinese state media, Global Times, was directly trying to interfere in our election by injecting various narratives into it, I'm not sure how that fits with those thresholds. I unfortunately can't comment on that.
My understanding, from reading the publicly available information, is that when that threshold is met, the political parties involved and the candidates who are targeted are notified, and the public is notified.
