The Supreme Court has interpreted the term 'liberty' in a broad and inclusive manner.

The right to personal liberty includes the right to freedom of movement, the right to freedom of expression, the right to freedom of association, the right to privacy, and the right to liberty and security of person.

The Supreme Court has also held that the right to life is not absolute and can be subject to reasonable restrictions imposed by law in the interests of public order, morality, and health. However, the Court has held that the right to life cannot be infringed except in accordance with the procedure established by law.
