Translated from Dutch Vroege Vogels TV:
The Utrecht District Court prohibits the gassing of geese
Thursday, March 22, 2018
The Utrecht District Court has forbidden the gassing of greylag geese, Canada geese and feral domestic geese. The Province of Utrecht had granted permission for this to the Fauna Management Unit [hunters] up to and including August 2019. …
In October last year, the Council of State already ruled that the province had erroneously granted an exemption to shoot many tens of thousands of geese with the same argumentation. The Supreme Court then ruled that no evidence was put forward which would show that the numbers of geese and with it agricultural damage would decrease sharply. New arguments to be able to kill geese again have been declared unfounded by the court ruling today.
