Whether the actions uncovered by the Snowden 'expose' is legal or not is a minor detail at this point...
if it is illegal then the immoral actions of the various surveillance organisations are illegal as well immoral
if it is legal then the immoral actions of the various surveillance organisations are legal and immoral, and in addition the legal framework is also immoral and in need of ripairs (sic).
As far as I understand this ruling, the tribunal has found both the ongoing actions of our watchers and the legal system to be inconsistent with the will and well-being of the people.
I am not holding my breath that either will be changed anytime soon.
