The issue is not competition or even wireless-related at all. There is a Federal Law specifying some minimum requirements. The cabinet decided that we will give a one-time exception to a particular private company, and allow them to break the law. A federal judge said: no, cabinet cannot do that, if they want to make exceptions in law, they have to do it the proper way: pass a bill, through parliament.
I think this is a great decision since this gives more power to the democratically elected parliament, as opposed to a chosen Cabinet.
(If the ruling party controls only 30% of the votes, they shouldn't have carte blanche to do anything they want, esp. breaking laws)
