How Judge Doty decides

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

What persuades

On a renewed motion to dismiss, Doty treats fact-bound equitable defenses (in pari delicto, apportionment of fault) as unsuited to the pleading stage — they require a developed record. A defendant who needs the court to weigh competing culpability to win dismissal will usually have to wait for summary judgment.

“At this stage in the proceedings, however, the court cannot determine the extent to which Associated Bank participated in and benefitted from the Ponzi scheme. ... As a result, dismissal on the basis of in pari delicto is not warranted at this time.”

Denies leave to amend as futile when the proposed amendment could not survive a motion to dismiss. Moving to amend in front of him requires a viable theory, not just a new label — futility is an independent ground for denial.

“An amendment is futile when it would not survive a motion to dismiss. ... Because Hennepin County is no longer a defendant in this case, however, Joiner has no basis on which to proceed with the conspiracy claim. As a result, the amendment would be futile and the motion to amend must be denied.”

Procedural preferences

Strictly enforces the magistrate judge's pretrial scheduling order. A party that fails to respond to a dispositive motion within the scheduling-order window risks having it granted by default, and a late extension request must clear Rule 6(b)'s excusable-neglect bar — months of delay will not.

“Plaintiff attempted to seek an extension more than four months after the deadline to respond had passed. ... Finally, plaintiff’s pro se status does not excuse him from complying with court orders.”

Requires a summary-judgment movant to actually carry the Celotex burden of identifying the record basis for the motion; a conclusory MSJ asserting the opponent has no defense is summarily denied.

“The court summarily denies the motion because Joiner has failed to support his motion as required.”

Cautions

Holds pro se litigants to the same procedural and limitations rules as represented parties: pro se status does not toll a statute of limitations or excuse non-compliance with court orders. Liberal construction of pro se pleadings does not extend to forgiving missed deadlines or unpleaded elements.

“A plaintiff’s pro se status does not constitute grounds to equitably toll the statute of limitations.”
