53. In circumstances where the Commission files a case before the Court pursuant to Article 5 (1) (a) of the Protocol, Article 3 (1) of the same provides no additional requirements to be fulfilled before this Court exercises its jurisdiction. Article 58 of the Charter mandates the Commission to draw the attention of the Assembly of Heads of State and Government where communications lodged before it reveal cases of series of serious or massive violations of human and peoples' rights. With the establishment of the Court, and in application of the principle of complementarity enshrined under Article 2 of the Protocol, the Commission now has the power to refer 2 See Alex Thomas v United Republic of Tanzania (Judgment on Merits) 20 November 2015 (hereinafter referred to as A lex Thomas Case) paragraph 45 and Mohamed Abubakari v United Republic of Tanzania (Judgment on Merits) 3 June 2016 (hereinafter referred to as Mohamed Abubakari Case) paragraphs 28 and 35. any matter to the Court, including matters which reveal a series of serious or massive violations of human rights.3 The Respondent's preliminary objection that the Commission did not comply with Article 58 of the Charter is thus not relevant as far as the material jurisdiction of the Court is concerned.
