How Judge Gaddy decides

Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.

What persuades

In Garner’s felon-in-possession case, Judge Gaddy recommended denying a facial and as-applied Second Amendment challenge to Section 922(g)(1) under binding Eighth Circuit decisions. He also noted Garner’s recent violent felony convictions would defeat an individualized challenge even if one were available.

“Even if Eighth Circuit precedent allowed for an ‘as-applied’ challenge for non-violent offenders or offenders with older felony convictions, this type of challenge would likely be unavailable or unsuccessful in this case.”

In United States v. Garner, Gaddy recommended denying a motion to suppress after finding that marijuana odor from Garner's vehicle supplied probable cause to search it under the automobile exception.

“the odor of marijuana emanating from Defendant’s vehicle provided Officer Schmidli with probable cause to search the vehicle for evidence of marijuana-impaired driving under the automobile exception.”

Procedural preferences

In Rosas, Judge Gaddy denied a recusal request raised in the closing paragraph of a dismissal motion because Rosas supplied no legal authority or factual basis for recusal and Gaddy found no personal knowledge or bias requiring it.

“Defendant’s failure to provide any legal authority or factual basis for the undersigned to recuse is fatal to his request.”

Cautions

In United States v. Thompson, Gaddy recommended denying suppression after finding the defendant's testimony about consent not credible and the detectives' testimony credible.

“the undersigned finds Defendant’s testimony was not credible and that the testimony of Detectives Lanaman and Love was credible.”

At a competency hearing, both sides stipulated to consideration of an updated psychiatric report and offered no additional evidence. The report found that symptoms continued to prevent the defendant from understanding the proceedings or assisting in his defense and that restoration was unlikely in the foreseeable future. The magistrate judge recommended a dangerousness examination and continued commitment; the district judge adopted the recommendation in full on March 18, 2026.

A snapshot on that date: matters listed may since have been decided or reassigned. A motion referred to a magistrate judge is counted for both judges. Motions in multidistrict litigation, section 2255 cases and Social Security appeals are not counted, and a very large three-year count is generally a multidistrict docket.
