You believe that the possibility of economic harm to businesses is in itself justification for the invocation to Emergency act?

What I am unclear about, as a non Canadian, is what the ruling means. For instance is there anything about the ruling, as it stands, to prevent or impede the government, in any way, from invoking the emergency act in future as long as they have a majority in parliament? If the ruling has no teeth why does the government care about it. Why even appeal it?
