A Bundestag committee whose four members, not mandatorily Bundestag members, are appointed by the Bundestag’s intelligence-agencies-monitoring parlamentarisches Kontrollgremium. The G10 committee monitors compliance with the German constitution’s requirement for individuals’ rights to letter secrecy [Briefgeheimnis], postal secrecy [Postgeheimnis] and telecommunications secrecy [Fernmeldegeheimnis].
The G10 committee supposedly must approve each surveillance or search of German citizens’ phones or computers by Germany’s intelligence agencies, which can only be possible if such surveillance is done on a very small scale. In July 2013, Spiegel-Online wrote that only 156 surveillance actions were approved by the G10 committee in 2011. And that the foreign intelligence service BND is permitted to ask for broadly-defined surveillance that is not however allowed to exceed 20% of the information out there and usually supposedly hovers at only 5%.
