Animal law and using the law to protect the lives and advance the interests of animals. In the Swiss canton of Zurich an animal lawyer, Antoine Goetschel, was employed by the canton government to represent the interests of animals in animal cruelty cases from 2007 to 31 December 2010, when the Zurich Animal Advocate position was abolished. In this capacity, Goetschel attempted to ensure that Swiss animal protection laws, which are among the strictest in the world, were correctly enforced.
