$\large\bf\color{Red}{Hey\: Friend}$

If you are asking about the Indian Constitution then:--

Article 21 of Indian Constitution says that:--
No person shall be deprived of his life and personal liberty except according to procedure established by law.

But,

If you are asking about Britain's Draft Article 21 then:--

Draft article 21 states that Each house shall elect its own Chairman and Deputy Chairman and shall prescribe their powers, duties and terms of office.

Answer 2

The Constitution of India provides Fundamental Rights under Chapter III Article 21. Protection of Life And Personal Liberty: No person shall be deprived of his life or personal Liberty except according to procedure established by law.... It clearly means that this fundamental right has been provided against state only.
