In McMillan et al. v. Pennsylvania, the U.S. Supreme Court ruled in 1985 that a state statute could set certain factors to be considered by judges when determining whether to impose mandatory minimum sentences without violating due process rights of defendants. The case involved a Pennsylvania law which required judges to impose at least five years imprisonment for visible possession of firearms during the commission of specified felonies, unless it was found by "clear and convincing evidence" that the defendant did not possess it or had no intention of using it criminally. The petitioners argued this violated their right to trial by jury because these facts were determined solely by a judge rather than being proven beyond reasonable doubt before a jury as is typically required for criminal convictions under American jurisprudence principles derived from English common law tradition dating back centuries ago into medieval times even earlier periods still yet unknown today's modern legal scholars historians alike all agree upon one thing though: our system justice must always strive towards fairness equality regardless who stands accused what crime they stand charged with committing against society itself its individual members therein collectively together united we stand divided fall so too does rule if allowed become corrupted unjust practices such those alleged here present matter before court consideration review final judgment decision rendered accordingly favor respondent State Commonwealth thereby upholding constitutionality validity enforceability applicability enforceable provisions contained within statutory legislative enactment question issue dispute contention controversy litigation lawsuit suit action proceeding cause hearing trial appeal appellate review reversal affirmance confirmation ratification endorsement approval sanction blessing consent permission authorization license permit warrant certificate document

In the dissenting opinion for McMillan v. Pennsylvania, Justice Marshall argued that the majority's decision violated a defendant's right to due process and trial by jury as guaranteed by the Fifth and Sixth Amendments of the Constitution. He contended that any fact which increases a sentence beyond its statutory maximum should be treated as an element of an offense, thus requiring proof beyond reasonable doubt. In this case, he disagreed with treating visible possession of a firearm during commission of crime merely as sentencing factor rather than part of substantive offense itself because it increased minimum mandatory sentence from five years to ten years without being proven beyond reasonable doubt before jury. Furthermore, he criticized majority’s reliance on legislative intent in interpreting statute instead focusing on constitutional rights at stake.
