Technical objections to procedural steps should not be permitted, in the absence of prejudice, to interfere with the expeditious and inexpensive decision of cases on their real merits. Where parties provide a credible explanation for failure to comply with procedural requirements (such as a family understanding between related parties), and where they have been in long-term occupation of disputed property, a special plea in bar based solely on non-compliance with estate administration procedures should not preclude a full hearing on the merits. The interests of justice require that disputes over valuable immovable property be fully ventilated rather than dismissed on technical grounds, particularly where lay persons may have acted in ignorance of legal requirements but not contrary to law or public policy.
