Suicide intervention is a direct effort to prevent a person or persons from attempting to take their own life or lives intentionally. Most countries have some form of mental health legislation which allows people expressing suicidal thoughts or intent to be detained involuntarily for psychiatric treatment when their judgment is deemed to be impaired. These laws may grant the courts, police, or a medical doctor the power to order an individual to be apprehended to hospital for treatment. This is sometimes referred to as being "committed". The review of ongoing involuntary treatment may be conducted by the hospital, the courts, or a quasi-judicial body, depending on the jurisdiction. Legislation normally requires police or court authorities to bring the individual to a hospital for treatment
