During his service in the Supreme Court of Appeal, Bosielo was thrice nominated unsuccessfully for possible elevation to the Constitutional Court. He was first interviewed for the apex court in June 2012, as one of four candidates, alongside
Raymond Zondo,
Mandisa Maya, and
Robert Nugent, for the vacancy created by
Sandile Ngcobo's resignation. The Judicial Service Commission recommended all four candidates as suitable for appointment, but President
Jacob Zuma elected to appoint Zondo. Bosielo was next shortlisted and interviewed in February 2013, one of five candidates for
Zak Yacoob's seat on the Constitutional Court, and he was again recommended for appointment on that occasion, alongside
Brian Spilg,
Selby Baqwa, and
Mbuyiseli Madlanga. However, President Zuma again declined to appoint him, elevating Madlanga instead. Finally, in October 2016, Bosielo was the most senior of four candidates shortlisted to succeed
Johann van der Westhuizen on the Constitutional Court; the other candidates were
Steven Majiedt,
Malcolm Wallis, and
Jody Kollapen. However, his interview with the Judicial Service Commission was diverted by discussion of a complaint which had recently been lodged with the commission and which related to Bosielo's involvement in a
black economic empowerment deal with mining company
Northam Platinum in his home village of Phalane, North West. His wife was a director in a connected company, but he denied that he had personally benefited from the deal. However, two commissioners – politician
Julius Malema and Chief Justice
Mogoeng Mogoeng – suggested that Bosielo ought to resolve the complaint before availing himself for Constitutional Court service, and, after intense questioning, Bosielo agreed to withdraw from contention. After Bosielo's death in 2018, the
Office of the Chief Justice reported that the Judicial Service Commission had investigated the complaint against Bosielo and had cleared him of any wrongdoing. == Personal life and death ==
