Jointer v. Superior Court, 158 Cal. Rptr. 3d 778

Defendant Michael Jointer was convicted in 1998 of second‑degree robbery with a firearm enhancement and sentenced to 34 years to life.
In 2012 Jointer moved under Penal Code 1405 for DNA testing of a water bottle found at the crime scene; the trial court denied the motion.
At trial, key evidence included fingerprints on the water bottle, eyewitness identifications (one in court, two tentative), and surrounding circumstantial evidence.
Police actions included photographing and dusting for fingerprints, a six-person lineup leading to an in-court identification, and a search of Jointer’s residence with related items found.
The appellate court held the trial court abused its discretion by denying testing, applying Richardson’s standard that a favorable DNA result could reasonably affect the outcome; the petition for writ of mandate was granted.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the 1405 motion should have been granted.	Jointer: DNA testing could yield a favorable result.	Orange Co.: other strong evidence suffices to convict.	Yes; the court abused discretion and granted the writ.
