Gauger v. Hendle, 954 N.E.2d 307

Gauger was convicted of his parents’ 1993 murders and sentenced to death, later reduced to life without parole, with a Governor’s pardon in 2002 based on innocence.
Federal authorities uncovered information in 1995–1997 tying other individuals to the murders, leading to later exonerating developments.
In 2003 Gauger filed a state-law malicious-prosecution suit against Hendle, Lowery, Pandre, the McHenry County Sheriff, and County of McHenry; trial focused on malicious prosecution, conspiracy, and indemnification.
The trial began August 12, 2009; evidence centers on whether defendants had probable cause and whether malice existed, including alleged police coercion and fabricated evidence.
The jury returned a verdict in defendants’ favor on all counts on August 20, 2009; Gauger appealed arguing evidentiary exclusions biased the result, which the appellate court affirmed.
The appellate court held the trial court did not abuse its discretion in excluding the Rule 23 order and the Outlaw evidence, and affirmed the judgment.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether exclusion of the Rule 23 order was erroneous	Gauger argues the order showed lack of probable cause and was law of the case.	Gauger’s claim invokes different issues (arrest vs. prosecution); order is not controlling.	No abuse of discretion; law-of-the-case/collateral-estoppel limits did not require admission.
Whether collateral estoppel/law-of-the-case precluded exclusion	Gauger contends the ruling on probable cause should have been law of the case.	The civil case differs from the criminal case; issues and standards differ.	Law-of-the-case and collateral estoppel did not apply.
Whether exclusion of the Outlaw evidence on malice was error	Gauger contends Outlaw details support an inference of malice by showing fabrication.	Outlaw evidence would confuse the jury and is not probative of coercion/malice under Porter/Aguirre.	Exclusion was not an abuse; not probative to establish malice given the stipulation and other evidence.
Whether exclusion of discovery of the ‘real killers’ evidence affected malice	Gauger claims the jury needed the full picture to infer malice.	Lack of link between real-killers evidence and Gauger’s police misconduct; risk of mini-trial.	Exclusion did not prejudice; court avoided a mini-trial and remained within discretion.
Whether the jury instruction on malice was correctly given			Not addressed on appeal because no new-trial remand; instruction deemed non-essential to GM.
