Remedy is not just relief, it is the means of obtaining relief.
“The ideas of right and remedy are inseparable. ‘Want of right and want of remedy are the same thing.’” (Edwards v. Kearzey (1877) 96 U.S. 595, 600) “‘Remedy’ is a more extensive term and refers to the method by which the action is effectuated. (Frost v. Witter, 132 Cal. 421.) ‘Remedy’ is not redressed or relief, but is the means by which a wrong is redressed and relief obtained.” (Painter v. Berglund (1939) 31 Cal.App.2d 63, 70)
There are many vehicles to obtain relief. They come in different names, but no matter what, one thing matters most.
“Call it a motion for a new trial, arrest of judgment, mandamus, prohibition, coram nobis, coram vobis, audita querela, certiorari, capias, habeas corpus, ejectment, quare impedit, bill of review, writ of error, or an application for a Get-Out-of-Jail Card; the name makes no difference. It is substance that controls.” (Melton v. United States, (7th Cir. 2004) 359 F.3d 855, 857)
