Friedman applied for employment at a pharmaceutical warehouse. He was offered a position and told that, as a condition of employment, he would have to be vaccinated against the mumps. He refused to be vaccinated because the vaccine is grown in chicken embryos. He said that it would violate his system of beliefs as a vegan, which prohibits the use of any animal-related product. The employment offer was withdrawn; he sued for discrimination based on religion. The district court dismissed the case, holding that veganism is not a religion. Friedman appealed.
Does he have a case? [Friedman v. So. Cal. Permanente Medical Group, 102 Cal.App.4th 39 Ct. App., Calif. (2002)]
