Der Senat Giffey beschloss 2021 die Einsetzung einer 13-köpfigen Expertenkommission
Correction

This date is wrong: the Giffey Senate was sworn in on December 21, 2021, and it formally decided to establish the commission on March 29, 2022, not in 2021.

Full reasoning

The article attributes the decision to establish the commission to the Giffey Senate in 2021. But the official Berlin Senate press release says the Senate resolved on March 29, 2022 to convene the expert commission on implementing the referendum. Separately, Berlin’s official press release on the formation of the Giffey Senate says Franziska Giffey was elected Governing Mayor and her Senate took office on December 21, 2021. So this Senate could not have made that formal decision earlier in 2021, and the official decision date is documented as March 29, 2022.

Philip P. Metzger: Wohnkonzerne enteignen! Wie Deutsche Wohnen & Co ein Grundbedürfnis zu Profit machen. Berlin 2011
Correction

The year is wrong. This book was published in 2021, not 2011.

Full reasoning

This bibliography entry lists Philipp Metzger’s book as Berlin 2011, but independent bibliographic sources identify the book as a 2021 publication. A review hosted by SoZ describes the book as: “Wien: Mandelbaum, 2021.” A TU Wien repository entry for a later scholarly review likewise names the book as “Metzger, Philipp P. (2021): Wohnkonzerne enteignen! …”. So the article’s publication year is off by a decade.
