Under which section of the MHA can a Judge order the examination of a person?

The correct choice indicates that a Judge can order the examination of a person under Section 22 of the Mental Health Act (MHA). This section provides provisions for a judicial examination, ensuring that individuals who are suspected of having mental health issues can undergo an assessment to determine their mental state and any necessary interventions.

In this context, Section 22 is significant because it establishes a legal framework that allows for the protection of individuals who may require mental health assessments. Such a mechanism supports the rights of individuals and ensures that appropriate evaluations are conducted in a structured and lawful manner. This process is vital for ensuring the individual's wellbeing while adhering to legal protocols.

The other options, while related to different aspects of the MHA, do not pertain specifically to the Judge's authority to order an examination. Each section serves its particular role, but Section 22 distinctly focuses on the judicial process related to mental health assessments.
