Whether the norm expressed in canon 1103 is of natural law or of positive Church law

The question of the legal origin regarding nullity of the coerced marriage has been discussed since the middle ages by theologians and canon lawyers. The interpretation of canon 1103 of the 1983 code on november 25, 1986 by Pontifical Commision for the authentic interpretation of the code of canon law permits this canon to be applied to coerced marriages of non-catholics. Since the 1983 code of canon law does not apply to the marriages of non-catholics, canon 1103 cannot be applied to these marriages unless it has its legal origin of nullity in the natural law.
