It Is The Peculiar Province Of The Legislature To Prescribe General Rules For The Government Of Society; The Application Of Those Rules To Individuals In Society Would Seem To Be The Duty Of Other Departments.

Let The End Be Legitimate, Let It Be Within The Scope Of The Constitution, And All Means Which Are Appropriate, Which Are Plainly Adapted To That End, Which Are Not Prohibited, But Consist With The Letter And Spirit Of The Constitution, Are Constitutional.

An Unlimited Power To Tax Involves, Necessarily, A Power To Destroy; Because There Is A Limit Beyond Which No Institution And No Property Can Bear Taxation.

Have No Power, By Taxation Or Otherwise, To Retard, Impede, Burden Or In Any Manner Control The Operations Of The Constitutional Laws Enacted By Congress.

The Constitution Is Either A Superior Paramount Law, Unchangeable By Ordinary Means, Or It Is On A Level With Ordinary Legislative Acts, Alterable When The Legislature Shall Please To Alter It. It Is Emphatically The Province And Duty Of The Judicial Department To Say What The Law Is. This Is The Very Essence Of Judicial Duty.
