The right to rest is undoubtedly one of the most fundamental rights of every person. The ecclesiastical legislator regulated this right in the following: Canon 283 para. 2; Canon 395 para. 2; Canon 410; Canon 533 para. 2; Canon 550 para. 3 of the 1983 Code of Canon Law. Thirty-three Polish post-CIC synodal legislators recited code dispositions, promulgating detailed regulations on leaves and days off for members of the clergy. The exercise of the right must always take into account the principle of salus animarum suprema lex.
