German Democratic Regime

After the Federal Chancellor is approved, he or she forms the government from the members of the winning party or from the coalition that elected him to this post. Ministerial candidates are approved by the Federal President.
If the Bundestag cannot agree on the candidacy of the Chancellor (three votes do not determine the winner), then the federal president can dissolve the Bundestag and call new elections. In addition, the Bundestag is disbanded if it expresses no confidence in the chancellor. Then new elections are called and a new ruling coalition is formed and a new chancellor is elected.
The independent nature of this body is represented by the fact that the German Bundestag established 23 permanent committees on 17 January 2018, which then held their constituent sittings on 31 January and commenced their work. These were joined on 25 April 2018 by a 24th committee in the form of the Committee on Building, Housing, Urban Development and Local Government. In addition, the Parliamentary Advisory Council on Sustainable Development was set up on 25 April 2018 and the Study Commissions "Artificial Intelligence – Social Responsibility and Economic Potential" and "Vocational Training" were established on 28 June 2018.
On 21 November 2017, the Bundestag had already set up a Main Committee with 47 members, a Committee for the Scrutiny of Elections, Immunity and the Rules of Procedure, and a Petitions Committee for the period until the establishment of the permanent committees.
In conclusion I can once again give the positive answer to the question “Do the work and competences of the Bundestag comply with the democratic principle of separation of powers?” It is proved by the following facts:
the existence of three separated branches,
the nature of the process and elections to the Bundestag,
the articles of the Basic Law which sets the democratic system in Germany,
a number of the particular rules of the Bundestag functioning covering only those spheres, for which this body is responsible,
the division of the areas of influence of each branch of power in the state.
