A German coalition agreement cannot be enforced in court. The first one in the Federal Republic, in 1961, had fewer than ten pages. The agreement of 2018 had 175 pages, and the one of 2021 had 177. On 5 May 2025, CDU, CSU and SPD signed their agreement of 144 pages in Berlin. Before that, the SPD had put it to a vote of its members, and 84.6 percent of those who voted approved. In October 2025, the coalition argued about a pension package. The SPD leader Lars Klingbeil said that Labor Minister Bärbel Bas had implemented was im Koalitionsvertrag steht, what is in the coalition agreement. He said it was the job of the CDU/CSU group leader to make sure dass seine Fraktion das verabredete Paket mitträgt, that his group supports the agreed package. The Bundestag passed it on 5 December 2025.
