There are circumstances where a protest could be on a national scale. It could, on a national scale, implicate, for example, critical infrastructure.
On the presence of the word “lawful”, as was the issue in 2001, the justice ministry took the view on the word “lawful” that an unlawful act could include a wildcat strike. It could include a street protest. That was the advice given by the Department of Justice in 2001. That's why the word “lawful” was omitted in 2001 from the definition of terrorist activity.
