Larceny Intent Timing
Tara Tran grabs a wallet from Theo Thomas at a bus stop. She forms the plan to keep the cash only after opening it later that night. Because the intent to permanently deprive must exist at the moment of the taking, the larceny charge fails.
Patent Term Limit
Theresa Tucker invents a new battery and seeks protection under federal power. Congress grants exclusive rights for a limited period measured in years from the filing date. The fixed duration balances innovation incentives against public access.
Reply Deadline Calculation
Tonya Takahashi receives a court order requiring a reply to an answer. She must serve the reply within twenty-one days after service of the order. Missing this window bars the reply absent a different time specified by the court.
Tabitha Taylor, a sitting judge, accepts a campaign contribution from a frequent litigant. She must act at all times to promote public confidence in judicial impartiality. The ongoing duty requires avoiding even the appearance of favoritism.
Confidential Information Bar
Tiffany Torres, a former government lawyer, learns confidential details about a company while in public service. She later seeks to represent a rival client adverse to that company. The prohibition applies when the information could disadvantage the subject at the time of the new representation.
Future Interest Duration
Trinity Pharmaceuticals receives a conveyance of land terminable upon an event certain to occur but not within any fixed period. The interest lacks a computable end date measured by lives or calendar time. The estate therefore fails to satisfy the rule against perpetuities.
