Prior to his election, he served as the House's Vice President and subsequently as Acting President, stepping into the role following the passing of the previous President, the Paramount Chief of the Shai Osudoku Traditional Area.
Initially, Ga Mantse King Tackie Teiko Tsuru II had submitted his candidacy for the position.
However, he later withdrew his application through a letter addressed to Mrs Gladys Pinkrah, Greater Accra Regional Director of the Electoral Commission, which allowed Professor Welentsi III to assume the presidency unopposed.
Professor Welentsi III's term as GARHC President will last four years, as stipulated by Act 759 of 2008, which mandates a presidential election for the House every four years.
