Congress Enforces Voting Rights
After the Nineteenth Amendment barred denial of the vote on account of sex, Congress enacted a statute requiring states to register women on the same terms as men. State election officials who refused to comply faced federal enforcement actions. The legislation directly implemented the amendment's command.
Legislature Declines to Exclude Justification
State legislators considered but ultimately omitted any provision excluding the necessity defense from reckless-endangerment prosecutions. When Lars Lindstrom later drove through a barricade to escape a wildfire, the court applied the justification because the legislature had not plainly excluded it. The statute's text reflected that deliberate legislative choice.
The state legislature enacted a statute providing that contingent-fee agreements to secure passage of bills are unenforceable. Legacy Motors had promised such a fee to a lobbyist. When the lobbyist sued after the bill failed, the court refused enforcement because the legislation had declared the contracts void.
Legislature Sets Emission Limits
The state legislature passed an environmental statute establishing maximum emission levels for industrial plants. Lakeshore Industries operated a plant that exceeded those limits. A neighboring homeowner sued in negligence, and the court treated the statutory limits as the standard of reasonable conduct.
Legislature Draws District Lines
The state legislature enacted a redistricting statute that created malapportioned districts. Voters sued state officials claiming vote dilution. The court rejected a political-question defense and allowed the case to proceed because no factor in the six-part test barred judicial review of the legislative districting.
Legislature Enacts Acts Given Full Faith
The legislature of State B enacted a statute that formed the basis of a judgment in State A's courts. When the prevailing party sought enforcement in State C, the court authenticated the State B statute by seal and gave it the same effect it would receive in State B's own courts.
