If will go through, trust me.
The courts don't have a choice. The EU market means that any EU citizen has the right to move between member states and there is also the freedom of movement of goods and services.
Therefore, if there is a TV broadcaster in the EU that is willing to supply its service in the UK they are bound to let it go through. They can't put any form of protection up. They can't even use ways to indirectly discriminate against foreign goods and services because its illegal unless they can claim there is some form of public policy or health issues. Which, it doesn't seem there is.
And if they ask the European Court of Justice to make a reference on the matter, they are inevitably going to turn around and say that the supply of satellite TV is covered by goods and services.
