"Without a functional judicial system, we have no recourse or accountability. Justice in Pakistan is delayed and denied."

The judiciary is the system of courts that adjudicates legal disputes/disagreements and interprets, defends, and applies the law in legal cases.
"John Marshall has made his decision: now let him enforce it!"
"The great object of my fear is the federal judiciary. That body, like gravity, ever acting, with noiseless foot, and unalarming advance, gaining ground step by step, and holding what it gains, is ingulfing insidiously the special governments into the jaws of that which feeds them."
"The germ of dissolution of our federal government is in the constitution of the federal judiciary; an irresponsible body, (for impeachment is scarcely a scare-crow,) working like gravity by night and by day, gaining a little to-day and a little to-morrow, and advancing its noiseless step like a thief, over the field of jurisdiction, until all shall be usurped from the States, and the government of all be consolidated into one."
"If the policy of the government, upon vital questions affecting the whole people, is to be irrevocably fixed by decisions of the Supreme Court,… the people will have ceased, to be their own rulers, having, to that extent, practically resigned their government into the hands of that eminent tribunal. Nor is there, in this view, any assault upon the court, or the judges. It is a duty, from which they may not shrink, to decide cases properly brought before them; and it is no fault of theirs, if others seek to turn their decisions to political purposes."
