that in the US
you can still claim a certain degree of protection from other users,
whereas here we can't.

The following is just an informal observation...

Here in the USA, we have two regulatory agencies for radio: FCC, which
does non-government radio, and NTIA, which does government/military
radio. NTIA trumps FCC, of course. The radar-interference case
mentioned elsewhere in this thread clearly shows who has priority on
the band in question.

But your question is about *commercial* (nongovernment) users/
intruders into the amateur bands, where such use is not part of the
regulations.

In theory, those intruders are breaking the law and should be removed
by the FCC. In practice, the FCC is complaint-driven, which means
amateurs must identify the intruder and complain to the FCC. Helping
with such complaints is one of the major functions of the ARRL and its
legal department.

But simply complaining to FCC does not mean the problem will be
solved, because FCC's resources are very limited. The motorsports
story referred to required a lot of work on the part of the ARRL and
the amateurs involved.
