- The majority affirms dismissal; concurring judge dissents on Davis’s qualified immunity.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Davis had qualified immunity for the arrest. | Shimomura argues no arguable probable cause. | Davis contends probable cause was arguable. | Yes; probable cause was at least arguable, supporting qualified immunity. |
| Whether Carlson can be liable for fabricating/exculpatory evidence to justify the arrest. | Carlson’s post-arrest conduct could not cause the arrest. | Carlson’s actions were not the cause of the arrest. | No plausible claim; Carlson not liable for unlawful arrest. |
| Whether there was a plausible pre-arrest conspiracy to arrest without probable cause. | There was a pre-arrest agreement between Davis and Carlson. | No plausible pre-arrest conspiracy given the arrest occurred within seconds of the incident. | No plausible conspiracy claim. |
| Whether Shimomura adequately pled a due-process claim under the Fifth/Fourteenth Amendments. | Due process rights violated by false arrest and charges. | Fourth Amendment governs pre-trial deprivations; no due-process claim. | No viable due-process claim; Fourth Amendment controls. |
