In what circumstances is a medical practitioner not obliged to give an employee access to a medical report prepared on him or her?

Under s.7 of the Access to Medical Reports Act 1988, a medical practitioner is not obliged to give an employee access to a medical report, or part of a report, prepared on him or her if, in the practitioner's opinion, this would be likely to cause serious harm to the physical or mental health of the employee or anyone else, or would indicate the intentions of the practitioner in respect of the employee. The medical practitioner is also not obliged to give such access if it would be likely to reveal information about another person, or to reveal the identity of another person who has supplied information to the practitioner about the employee, unless that person has consented, or is a health professional who has been involved in the employee's care and the information relates to, or has been provided by, the professional in that capacity.
