The words -procedure established by law- means:

That due process of law must be followed A procedure laid down or enacted by a competent authority The same thing as 'rule of law' A law which is reasonable, fair and just

A law which is reasonable, fair and just

A person can be deprived of his or her 'right to life or personal liberty' only by procedure established by law. This means that any law that limits or takes away one's right to life and personal liberty must contain a procedure that is fair and reasonable and not arbitrary. 'Rule of Law' essentially means that law carries supremacy over all individuals, even those in the position of power. The notions of equality and non-arbitrariness are also important and non-detachable components of rule of law.
