This paper discusses ethical issues related to social work practice in the area of mental health. It does so via the use of a case study taken from my practice whilst I was on placement. Ethical issues are explored within a practice context that is becoming increasingly proceduralised and risk averse, and where protectionist responses contribute to undermining the rights of service users to self-determination. The paper explores the relationship between utilitarian and Kantian ethical theory and ethical decision-making as well (...) as commenting on the usefulness of an anti-oppressive ethical perspective.
