State v. Maxim, 454 P.3d 543

Officers responded to an apartment manager’s report of suspected drug use where children lived and approached an apartment without a warrant.
An officer pushed the front door open after knocking, entered, and later encountered Maxim leaving a locked hallway bathroom; officer ordered Maxim to put his hands on his head.
While escorting Maxim to the door and after retrieving a knife from his pocket, the officer reached into the outturned pocket and removed a small silicone container later identified as heroin; Maxim then was handcuffed.
After arrest, officers learned Maxim was on probation and had signed a probation condition waiving Fourth Amendment rights; that waiver was unknown to officers at the time of the entry and frisk.
The district court denied Maxim’s motion to suppress, concluding discovery of the heroin was inevitable; Maxim pleaded guilty reserving the right to appeal suppression and appealed.
The Idaho Supreme Court reversed: it held an unknown probationary Fourth Amendment waiver cannot justify an otherwise unreasonable, warrantless home entry or search, and the State failed to prove inevitable discovery.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether a probationary Fourth Amendment waiver can retroactively justify an otherwise illegal warrantless entry/search when officers did not know of the waiver at the time	Waiver means Maxim lacked a reasonable expectation of privacy so no Fourth Amendment violation occurred	Waiver is consent affecting reasonableness, but officers’ lack of knowledge at the time means the entry/search was still unreasonable	Waiver unknown to officers at the time cannot render an otherwise unreasonable entry/search reasonable; cannot be used as a post hoc justification
Whether the inevitable-discovery exception saves the evidence	Even if search was illegal, police would have lawfully discovered the heroin via owner consent or subsequent lawful steps	Entry and discovery were not on a parallel, pre-existing lawful investigatory path; State’s theory was speculative	State failed to meet its burden; district court erred by relying on speculative timelines—inadmissible under inevitable-discovery doctrine
