After the 2015 ANCYL elective conference, Lamola disappeared from the public eye and subsequently managed his own law firm. In 2017, he endorsed Cyril Ramaphosa to become ANC President. In December of the same year, Lamola was elected to the National Executive Committee of the African National Congress (NEC). Shortly after, in January 2018, the ANC NEC appointed him to the party's National Working Committee, the party's highest decision-making structure. Following the May 2019 elections, Lamola took office as a Member of the National Assembly. President Cyril Ramaphosa appointed him to the post of Minister of Justice and Correctional Services on 29 May. He assumed the office on 30 May. Lamola married Bawinile “Winnie” Msiza at the Cunning Moor in Bushbuckridge, Mpumalanga, on 8 March 2013.
