Final answer:
A barrister must cease to act and return instructions if there is a loss of confidence, a conflict of interest, or a breakdown in the solicitor-barrister relationship.
Step-by-step explanation:
A barrister must cease to act and return instructions under certain circumstances. One of the main reasons is if the client has lost confidence in the barrister's ability to represent their interests effectively. Another reason is if there is a conflict of interest that arises during the case, meaning the barrister cannot continue to represent the client without compromising their professional obligations. Additionally, a barrister may be required to cease acting if there is a breakdown in the solicitor-barrister relationship, such as non-payment of fees or failure to provide necessary information.
