Understanding the Substantial Capacity Test in Legal Context
Definition & meaning
The substantial capacity test is a legal standard used to determine whether a person can be held responsible for their actions due to mental illness. According to this test, a person is considered insane if they lack substantial capacity to control their behavior or understand the wrongfulness of their actions. Essentially, it assesses the mental ability required to recognize that an act is against the law or to act in accordance with legal standards.
