Abstract
X, who works for Association Y on a promotional track, applied for reinstatement into Association Y twice during their leave of absence due to schizophrenia. Both applications were rejected, and the individual was treated as retired after the leave of absence period expired. This is a case in which a lawsuit was filed to the effect that this decision was illegal and invalid. In the judgment, all of X’s claims were dismissed as groundless, and the case of Japan Fishing Vessel Insurance Association (Tokyo District Court Judgment dated August 27, 2020), whose treatment of the individual as retired at the end of the leave of absence period was deemed valid although the attending physician judged that the individual could return to work, is examined here, with commentary provided.
