The article raises issues of waiver of appeal made by the marriage bond defender of the Appeal Court that was brought by the marriage bond defender of the first instance court. This is a problem that is currently subject to discussion due to the marriage process reform that took place in 2015. That problematic aspect must always be considered in the context of specificity of the canonical marriage process as well as responsibility for the decisions made. This also includes consideration of a social dimension of the judgement delivered by the Church that ought to present the truth concerning the appealed marriage. There is no doubt that waiver of appeal made by the marriage bond defender of the Appeal Court brought by the marriage bond defender of the first instance court seems to be exceptional in the light of historical, legal and doctrinal arguments presented in this article and cannot, at any time, lead to injustice in the Church judiciary, particularly in regards to matrimonial matters. After all, this is the marriage bond defender of the first instance court who is familiar with the case from its very beginning, follows its course of development and presents his remarks, including bringing appeal to the Church court of the second instance. For that reason, such an appeal should be treated with utmost responsibility. Arguments provided in the article that result from the current law, Magisterium of the Roman Church Bishops, and the position of the canonical doctrine indicate that dismissal of appeal by the marriage bond defender of the Appeal Court that is brought by the marriage bond defender of the first instance court ought to be a very exceptional and well justified situation. Despite existence of the indicated legal possibility, the Author of this article advocates for not using the canonical norm in the judicial practice of the Church, mainly due to the fact that it was promulgated at the time when there was an obligation to deliver two positive judgements in order to enter into a new marriage in the Church. That situation has changed after 2015. Due to this reason, there appear postulates for amending Canon 1636 § 2.
