Coker had a lucrative law practice in Lagos before he was appointed to the bench of High Court of Lagos in 1958.
In 1962, during a political crisis in the Western region of Nigeria, Coker was appointed by Moses Majekodunmi, the sole administrator of the region to chair a commission of enquiry into the affairs of some statutory corporations. The commission was viewed by some as an instrument to discredit the Awolowo faction of the Action Group. However, in the final report of the enquiry, it found Awolowo culpable in the diversion of regional funds to finance the Action Group but exonerated Akintola, which made it easier for the latter to be reinstated as Premier of the region. He became a justice of the Nigerian Supreme Court in 1964. At the apex court, Coker was notable for his judgements in stay of execution pending judgement cases. Two notable cases of the nature were Vaswani v Savalakh and Utilgas Nigerian And Overseas Gas Co. Ltd.v. Pan African Bank Ltd.
Coker was a member of the Methodist Church in Tinubu, Lagos.
