The Parliamentary Oversight Panel (PKGr) is a committee of the German Bundestag responsible for oversight of the intelligence agencies of Germany. The PKGr monitors the Federal Intelligence Service (BND; German: Bundesnachrichtendienst), the Military Counterintelligence Service (MAD; German: Militärischer Abschirmdienst), and the Federal Office for the Protection of the Constitution (BfV; German: Bundesverfassungsschutz). Under the Control Body Act [de] (PKGrG; German: Kontrollgremiumgesetz), the federal government is obliged to inform the PKGr comprehensively about the general activities of the federal intelligence services and about events of particular importance.

At the beginning of each legislative period, the German Bundestag elects the members of the Parliamentary Oversight Panel from among its members (Section 2 (1) PKGrG). It determines the number of members, the composition, and the working methods of the Parliamentary Oversight Panel (Section 2 (2) PKGrG). The Parliamentary Oversight Panel meets at least once every quarter. It elects a chairperson and their deputy. It adopts its own rules of procedure (Section 3 (1) PKGrG). Each member may request that the Parliamentary Oversight Panel be convened and informed (Section 3 (2) PKGrG).

To the extent that the right of control of the PKGr extends, it may demand that the Federal Government and the intelligence agencies hand over files or other documents in official custody, if necessary also in the original, and transmit data stored in files. It must be granted access to all offices of the federal intelligence services at any time (Section 5 (1) PKGrG). It may question members of the intelligence services, employees and members of the Federal Government and employees of other federal authorities after informing the federal government, or obtain written information from them. The persons to be heard are obliged to provide complete and truthful information (Section 5 (2) PKGrG).

Insofar as this is necessary for compelling reasons of access to intelligence or for reasons of protecting the personal rights of third parties, or if the core area of executive responsibility is affected, the Federal Government may both refuse to inform the PKGr about general activities and events of particular importance and to hand over files and transmit files, and also prohibit employees of the Federal Intelligence Services from providing information. The Federal Government must give reasons for both to the PKGr (Section 6 (2) PKGrG).

The members of the PKGr are regularly given an insight into the work of the federal intelligence services by the federal government. Since their work is naturally to remain secret, the members of the PKGr are bound to secrecy, even towards the other members of the Bundestag (Section 10 (1) PKGrG). Because the parliamentary right to ask questions also extends to the intelligence services, the federal government and the PKGr are obliged to provide information on urgent matters. According to the Federal Constitutional Court (German: Bundesverfassungsgericht)'s ruling 2 BvE 5/06,^[1] the federal government's argument that intelligence matters are to be discussed exclusively in the PKGr and not made public is inadmissible because the parliamentary right to ask questions also extends to the federal intelligence services.^[2] Three copies of the minutes of the PKGr's meetings are produced.^[3]

Employees of the federal intelligence services are permitted to address the Parliamentary Oversight Panel directly in official matters as well as in cases of internal grievances, without following official channels. They may not be reprimanded or discriminated against in the service because of the fact of their submission. Submissions from citizens to the German Bundestag concerning conduct by the federal intelligence services that affects them may be brought to the attention of the Parliamentary Oversight Panel (Section 8 PKGrG).

Within the scope of their departmental responsibilities, the Interior and Defense Committees also exercise a certain degree of control over the BfV and the MAD, respectively.

The PKGr can include transitional members who are no longer members of the Bundestag: In order to ensure uninterrupted oversight of the federal intelligence services, the Parliamentary Oversight Panel continues to carry out its activities beyond the end of an electoral period of the German Bundestag until the subsequent German Bundestag has decided on a new composition (Section 3 (4) PKGrG). Such a situation existed, for example, on October 24, 2013, when, in connection with the 2013 surveillance and espionage affair and indications of eavesdropping by the United States of America on Chancellor Angela Merkel, the FDP members of the 17th German Bundestag who had not been reelected to the 18th German Bundestag took part in a special meeting of the Oversight Panel during the legislative term of the 18th German Bundestag.

The PKGr is sometimes described as "toothless," i.e., without any real power. In the past, for example, intelligence services could sometimes only be visited with advance notice, and members of the PKGr reported that intelligence service employees had told them the untruth on several occasions.^{[21][22][23][24]}

Although the Control Body Act does not provide for sanctions in the event of non-compliance with information obligations by the responsible intelligence service employees and preventive control of intelligence-related ones. However, restriction measures under the Article 10 Act must in principle be approved in advance by the G 10 Commission. Although the PKGr cannot itself bring unlawful actions to criminal charges or order the publication of corresponding, confidential documents, it can call on the German government to put a stop to abuses.

In addition, there are calls for the PKGr to be given the rights of a committee of inquiry in order to be able to effectively investigate breaches of the law (currently, for example, no evidence can be collected or witnesses summoned). However, the German Bundestag has the right to set up committees of inquiry to investigate possible misconduct in the area of the federal intelligence services, which can take evidence and summon witnesses (Section 44 of the Basic Law). The Bundestag has already made numerous uses of this right, such as in the Murat Kurnaz case or in the so-called Plutonium affair. The Defense Committee can declare itself a committee of inquiry to investigate events in the MAD (Section 45a (2) of the Basic Law).

Organizations such as netzpolitik.org also criticize the fact that the PKGr is almost completely deprived of data on cooperation with foreign intelligence services, for example.^[25] Furthermore, it is critically noted that the PKGr controls the intelligence services of the federal government, but not other security agencies, which also sometimes use quasi-intelligence resources, such as the Federal Police, the Federal Criminal Police Office or the German Customs Investigation Bureau. In particular, increasingly far-reaching powers, in terms of online searches and source telecommunication surveillance by law enforcement agencies, raise the question of who actually monitors these measures, especially since the technology used is presumably the same. At any rate, the responsible Interior Committee of the German Bundestag does not currently receive any such information due to the secrecy interests of the federal government.^[26]

Time and again, information from secret meetings of the PKGr is leaked to the mass media and thus reaches the public, including from the report on the BND journalist scandal. This could lead to the federal government making more frequent use of its right to refuse to provide information (Section 6 (2) PKGrG). Thus, the behavior of individual PKGr members would run counter to the control purpose of the parliamentary body. The PKGr asked the Bundestag President Norbert Lammert in the so-called journalist scandal at the time, to initiate legal action, because of the suspected violation of official secrets (§ 353b StGB) by the illegal disclosure of information.^[27][28]
