This paper reviewed the extent to which Bolam provided healthcare professionals with immunity from claims based on negligence in the past, and whether Bolitho was able to resolve that issue.During the early 1950s, when the NHS was in its golden era, the medical profession was still “unregulated and paternalistic” in approach. Consequently, the medical profession had enjoyed unreserved obedience from patients and was treated with great reverence by society. John Hector Bolam was a patient who sustained fractures because the defendants applied unmodified electro-convulsive therapy on him. So, his suit for negligence provided the much-needed opportunity for grounding the principles of medical negligence which was still in its early stage of development. The issue was unprecedented, and therefore the dictum of Lord President Clyde in the Scottish case of Hunter and Hanley became handy. The ruling gave doctors the latitude to set standards of care and justify their actions by simply having their peers support them. It placed the onus of proving “Wednesbury unreasonableness” on the patients in order to succeed in medical negligence litigation against a doctor. That was very difficult to prove. This attracted criticisms against Bolam that it provided excessive immunity to doctors and difficulties to the patients. Several cases had been decided in favor of the doctors and allied healthcare professionals.A similar opportunity arose in 1984 when the Bolitho rule was propounded which empowered the courts to intervene and determine if a body of medical opinion is indeed responsible, by subjecting their evidence to the logicality and risk/benefit analysis tests.Issues for consideration include, to what extent did Bolam provide immunity to healthcare professionals and, post-Bolitho, if the issues have now been resolved. To accomplish that, the author will examine the various court decisions pre-and post- Bolitho with a view to coming up with the answer(s) to the issues raised
