The Seriousness Requirement in Constitutional Pleas as a Fundamental Mechanism for Activating Post-Litigation Constitutional Review in Algerian Law: An Analytical Study in Light of the 2020 Constitutional Amendment and Organic Law No. 22-19

This study examines the seriousness requirement as a central legal and procedural condition for activating postlitigation constitutional review of laws within the Algerian legal system.The research is grounded in the constitutional transformations introduced by the 2020 constitutional amendment and the procedural framework established under Organic Law No. 22-19, which governs the mechanism for raising pleas of unconstitutionality before judicial bodies and their referral to the Constitutional Court.The paper provides a conceptual and analytical examination of the seriousness requirement, highlighting its dual procedural and substantive nature and the criteria relied upon by judges to assess whether a constitutional plea merits referral.Particular attention is devoted to the role of this requirement in filtering frivolous, abusive, or malicious claims, thereby preventing procedural congestion and safeguarding judicial efficiency, while simultaneously ensuring effective constitutional protection of fundamental rights and freedoms.Furthermore, the study analyzes how the seriousness requirement operates as a juridical link between ordinary courts and the Constitutional Court, reinforcing institutional cooperation and strengthening the principle of constitutional supremacy.Through an examination of legislative texts, judicial practices, and doctrinal interpretations, the article demonstrates that the seriousness condition is not merely a formal threshold but a substantive guarantee that balances access to constitutional justice with procedural discipline.The findings of the study reveal that the seriousness requirement plays a decisive role in transforming the plea of unconstitutionality into an effective tool for rights protection and the consolidation of the rule of law in Algeria.However, the research also raises critical questions regarding the sufficiency of current criteria and the extent of judicial discretion in determining seriousness, suggesting the need for clearer standards to enhance legal certainty and uniform application.
