Clinicians should be aware of the inherent jurisdiction of the High Court in providing a ‘safety net’ to protect ‘vulnerable’ adults who are not within the scope of the Mental Capacity Act 2005 (MCA) or the Mental Health Act (MHA) 1983. Many situations in which the inherent jurisdiction has been deployed have been to safeguard vulnerable adults where there is abuse, coercion or undue influence, but the person does not lack decision-making capacity under the MCA. We explain the nature of the inherent jurisdiction, including descriptions of concepts surrounding ‘vulnerability’; as an intervention of last resort, we consider what statutory alternatives may exist, including safeguarding law under the Care Act 2014; we discuss decision-making capacity in relation to contact with others and, using real cases, the types of order that may be made under the court's inherent jurisdiction. It is important to be mindful that although there may be a legal remedy to safeguard this ‘vulnerable but capacitous’ group, there is a delicate and challenging balance between protecting those at risk and respecting their autonomy.
