In a referendum in September 2021, a good 59 percent of voters had voted for the socialization of real estate companies with more than 3,000 apartments in Berlin. After a good year of deliberation, a commission of experts appointed by the Senate came to the conclusion in June that such a socialization - i.e. expropriation in return for compensation - would be legally and constitutionally possible. According to this, the constitution allows for the state of Berlin to regulate the socialization of land in a law.
