Fagan was made a judge of the
Cape Provincial Division by
Prime Minister Smuts in March 1943. Yet, unlike many other judges with Afrikaner nationalist leanings, Fagan did not shun
English law on principle. and that
undue influence vitiates a
contract. But he did find against the government in its attempt to enforce the
Population Registration Act, 1950, raising the standard of proof required to classify a person as 'non-European' on the provocative basis that Parliament could not have intended something so unjust as foisting that status on a person without adequate proof. Fagan, too, had sat in this last case (but not in
Harris), and concurred in Centlivres' judgment. The lone dissentient was
Oliver Schreiner, a noted liberal judge of very high esteem. Schreiner was also the most senior judge on the Appellate Division after Centlivres' retirement, and was therefore first in line, according to long-standing convention, for appointment as Chief Justice. Yet he had plainly proven himself to be politically unsafe during this so-called
coloured vote crisis, and was, presumably as a result, passed over by the Nationalist government. This move was widely condemned. The next most senior judge, Hoexter, had joined Centlivres' judgment in
Collins, but had voted against the government in the
Harris cases, so he, too, was disfavoured. That left Fagan, untainted by any association with
Harris and with clear Afrikaner and Nationalist ties, who was offered the post by
Minister of Justice C. R. Swart. Fagan was shocked by the offer, describing it as a "bolt from the blue". In a letter to Swart, Fagan said he was faced with "a very difficult choice", noting his concerns about superseding the more senior Schreiner and the obvious implication that the offer was politically motivated. , who as Minister of Justice controversially appointed Fagan as Chief Justice, and who later defeated him in a Senate election in 1961 to become South Africa's first
State President.|200x200px In the end, after discussions with Schreiner, Fagan accepted the post. They decided it was best for him to accept the appointment, despite all its problems, to prevent notorious National Party favourite
L. C. Steyn becoming Chief Justice. Initially they had, at Centlivres' suggestion, tried to reach an agreement among the judges of the Court that they would all refuse appointment, so that the government would be forced to appoint Schreiner. But this plan failed, unsurprisingly, when Steyn refused to agree. Fagan therefore accepted the Chief Justiceship with misgivings. He wrote to his wife after his appointment that he still felt "sick about Oliver [Schreiner]" and ashamed when people congratulated him. == Retirement ==
