The VG Köln restored the suspensive effect of a lawsuit against a preventive house ban issued by a university to prevent potential disruptions of a lecture by the Israeli ambassador. The court ruled that measures based on university house rights (§ 18 HG NRW) require a viable danger prognosis of future disturbances, which cannot be based on mere "likes" of boycott calls or the previous use of the slogan "From the river to the sea". It further clarified that the intent to ask critical or unpleasant questions during a sanctioned discussion does not constitute a disruption of university operations per se. A house ban was also deemed disproportionate, as the university failed to establish why milder means—such as security checks or removing the person only in the event of an actual disturbance—would be insufficient.

§ 18 Abs. 1 Satz 4 HG NRW.
