Admissibility is the first test to having an individual complaint considered by international human rights mechanisms (courts/committees/commissions etc.)
Procedural admissibility factors include exhaustion of domestic remedies, time limits, duplication of proceedings, abuse of the right of application, and anonymous applications
Domestic remedies are considered exhausted when the same complaint was raised either expressly or at least in substance before the national courts in line with rules and procedures of domestic law
Time limits for submitting applications before international human rights mechanisms vary, such as 4 months for the ECtHR, 6 months for IACommHR, and different limits for the UN system bodies
Applications must be submitted without undue delay, and applicants must show diligence and initiative, especially in cases like enforced disappearances
A complaint is generally inadmissible if the same body or another body has issued a decision concerning the same matter, with exceptions in certain cases
The prohibition of abuse of the right of application aims to prevent harmful exercise of the right for purposes other than those for which it is established
Rule 47 RoP ECtHR para 4 states that applicants who do not wish their identity to be disclosed to the public must indicate so and provide reasons justifying this departure from the normal rule of public access to information
Jurisdiction under public international law is a key aspect of state sovereignty, involving authority over persons, legal relationships, and obligations
The European Court of Human Rights has jurisdiction ratione personae to examine human rights violations by a Contracting State or acts attributable to it, including those by state organs, local governments, private contractors, and private actors
Jurisdiction ratione loci allows the Court to examine violations of the Convention within the jurisdiction of the respondent State on its territory or in territory effectively controlled by it
Jurisdiction ratione temporis states that the provisions of the Convention do not bind a Contracting Party in relation to any act or fact which took place before the date of the entry into force of the Convention with respect to that Party
Manifestly ill-founded complaints can be categorized as "fourth-instance" complaints, complaints disclosing no clear violation, unsubstantiated complaints, and confused or far-fetched complaints
The Court may reject cases considered as "minor" under the criterion of no significant disadvantage, added with the entry into force of Protocol No. 14
The level of severity for a "significant disadvantage" violation is assessed based on the financial impact and importance of the case for the applicant
The safeguard clause prevents the Court from declaring an application inadmissible when respect for human rights requires an examination of the application on the merits
