It's not a judicial review, the PKG (parliamentary control committee) and the G10 Kommittee, which is a subset of the PKG, both consist of members of Parliament, and they do the same work (keeping an eye on the executive branch's work) - just for efforts whose information is considered too sensitive for wider distribution.

[dogma1138]

My german is a bit rusty but doesn't "gerichtlicher prüfung" translates into "court examination" or more precisely "judicial review"?

[pgeorgi]

"Die anstelle gerichtlicher Prüfung des Sachverhalts vorgesehenen politischen Kontrollgremien haben sich in der Vergangenheit aber oft als unzulänglich erwiesen:"

translates to (while keeping the sentence structure the same as much as possible, even if that sounds a bit off in english):

"The, in place of judicial review of the factual matter, arranged political control committees have shown in the past to often be insufficient:"

[germanier]

The Wikipedia article states (correctly) that there is no judicial review in the usual case. The parliamentary committee does not perform that.
