Apparently, it's Gauss's law, not (the) Gauss Law. I'm relying on Wikipedia here (and elsewhere), which sticks adamantly to the former. Please correct me in a comment if I'm wrong.
I think that to be consistent with all other such tags, e.g., coulombs-law, greens-functions, machs-principle, fermis-golden-rule, braggs-law, it should be tagged by gausss-law, not the current gauss-law.
It looks a bit funny though. :)
