The struggle of the governing coalition of SPD, Left and Greens to the planned Berlin Mietendeckel goes into the next round. The Senate Chancellery and the Senate Administration, headed by Andreas Geisel (SPD), have each filed legal doubts in their internal letter addressed to city development senator Katrin Lompscher (left) about their bill on the rental cover. As the regulations are now designed, neither they nor the SPD-led financial administration would sign the Senate bill.

Actually, the Lompscher draft should be signed by all concerned Senatsverwaltungen with an opinion until next Monday. Now Governing Mayor Michael Müller (SPD) and the two mayors Ramona Pop (Greens) and Klaus Lederer (left) have to strive again for a reconciliation of interests.

This could delay the timetable for the law: on 15 October, a joint Senate decision should be taken for the Mietenteckel before meeting on October 24, the Council of Mayors, which deals with its implementation in the Berlin districts. Afterwards, the House of Representatives must advise and pass the law. For the new regulation to come into force as planned in January 2020, this would have to be completed by December.

At the heart of the concerns of the SPD is the reduction in rents set out in the bill if these amount to more than 30 percent of the total income of the tenant's household. Because the purpose of this rule is to protect individual tenants with low incomes, this is social tenancy law - and that falls into the legislative competence of the federal government. The Interior Authority sees in the reduction of a disproportionate interference with the landlord.

The Senate Chancellery asks Lompscher to examine whether a draft for the Mietendeckel would be possible "who refrained from the possibility of lowering rents in existing contracts" - because the measure leads to legal uncertainty and arouse false expectations. In addition, the many expected test cases could mean immense administrative and legal costs. The Senate Chancellery prefers a "separate solution for cushioning individual hardships" - as its own bill for lower rent at a later date.

Cultural Senator accuses Müller Wortbruch

Culture Senator Klaus Lederer (left) accused Muller of breaking an appointment. Already on Tuesday, the Governing Mayor Lompschers design had denied in important parts of a refusal: He assumed that "the entire project to reduce the rents are taken out of the law," he said at the Association of the German real estate industry (ZIA).

The Berlin SPD will also vote on its position on the expropriation of large housing companies at its state party conference on 26 October. The request committee of the state board could not agree on a joint vote. So the comrades will have to choose between alternatives. Either they are committed to the initiative "expropriate Deutsche Wohnen & Co." as a partner and the means of socialization as a rental and housing architectural instrument. Or the congress holds the socialization of holdings of housing companies "currently not for purposeful", as it says in an application draft, which is the Tagesspiegel .

On Thursday, several thousand participants demonstrated in Berlin under the motto "Correct cover, then expropriate - red card for speculation".
