I can only report what it is that I've asked counterpart colleagues in Australia, the United Kingdom, and the United States when I posed the question whether their domestic security intelligence organizations have powers of disruption, and whether those powers of disruption are permitted to supersede either their domestic law or their constitutional rights. The answer from the United States, Australia, and the United Kingdom was no.
The closest analogy that an Australian colleague was able to point to was a new power that the Australian equivalent to CSIS has to delete material from a computer pursuant to warrant.
