The news is almost too good.
Indeed, I had to read it several times in extenso to fully grasp not only what has been decided by the German Supreme Court of Justice but also the implications of this court ruling.
If Germans hate something profoundly, this might be uncertainity. There must have been a lot of hate on the side of the judges, concerning many legal uncertainities pertaining to general IT, so they made a remarkably clear, direct, and comprehensive ruling. A few political commentators cannot recall a ruling this revolutionary since the post-war constitution has been adopted in Germany (1949).
Adhering to the aforementioned Constitution (or Grundgesetz), the judges defined a whole new class of citizens' rights. State institutions of every walk of bureaucratic life has been slammed with the necessity of implementation of these newly defined people's freedoms into their practice. A complete law (Gesetz) on the modus operandi of state police, barely two years old, has been declared unconstitutional and thus nullified by the supreme court.
It seems that the federal government will have to do a lot of homework reviewing the laws and regulations, and so will have each of the 16 province governments, too. The whole shebang is nothing short of revolutionary. It is even conceivable that spammers and crackers will be hit by it due to the fact that they seek to compromise the "informational integrity" of people's communication and data processing devices which is now verboten, and put under penalty.
Personally, I do not care that much about every minute detail of what exactly which state institution will - or won't - be allowed to do due to the new supreme court ruling. However, if the local Interweb spammers (bot hosts) will face jail, or at least compulsory cancellation of their broadband accounts, then the ruling's will undoubtedly have a strong positive effect on the general IT culture in Germany.
The security of data interchange is already up, and rising. The Germans are topped in the number of new, secure Linux installations probably only by the Polish. Due to the said court ruling the awareness of securely sound technologies could put the Germans into the top position in Europe, which is not bad at all.
However, I would abstain from speculating about other countries' experiences with their legislative bodies. That a court of justice defines citizens' freedoms, even broadens them considerably, is pretty much unique. Don't even try to understand it - this is a German specialty. You will have to move your MPs, congressmen, or members of whatever legislative body it might be to do the job. Parliamentary discussion might be a better tool to shape the future law then a court's ruling, which merely initiates the lawmaking procedure.
The initiative is ours. Let us get a strong support for security measures from the corresponding law, and augment our freedoms in a due course.
