You're not asking for the authority to accept you to march, you simply announce that you'll march, which, as a fundamental right, can't be rejected by the authorities beforehand unless there are serious reasons to believe that major trouble will occur. Though in the recent years several protests were forbidden by the authorities, it still is completely exceptional, and the marches happened anyway (and of course, major fights with the police ensued).

I agree with what you and your brother comment say, however you are both missing my 2 main points :) Which are that being a fundamental right it is easier to do and also the right is misused in my opinion, we should consolidate forces instead of striking in turn each year.
