How Judge Cannon decides

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

What persuades

On summary judgment she requires competent record evidence, not the movant's own testimony or speculation; a scintilla is not enough.

“Speculation does not create a genuine issue of fact; instead, it creates a false issue, the demolition of which is a primary goal of summary judgment.”

Procedural preferences

Each summary-judgment record is judged on its own facts; she will not import an outcome from a related case decided on a different record.

“that O'Leary's wrongdoing harmed multiple litigants in different proceedings does not obviate the Court's obligation to assess the particular factual record presented in each case under the applicable legal standards”

Conducts de novo review of objected-to portions of a recommendation but accepts unobjected portions when the face of the record shows no clear error.

“To the extent a party fails to object to parts of the magistrate judge’s report, the Court may accept the recommendation so long as there is no clear error on the face of the record.”

Cautions

Arguments raised for the first time in objections to an R&R (e.g., res ipsa loquitur) are disfavored and unlikely to rescue a record that lacks evidence of breach.

“Without foreclosing the application of res ipsa loquitur in the airline context writ large, what is clear is that the event as pled in this case is not a quintessential res ipsa event”

Monell failure-to-train/supervise liability faces a 'difficult-to-satisfy' notice standard and a backward-looking inquiry; post-arrest conduct cannot create the required pre-existing notice.

“an inquiry into Monell liability for failure to train/supervise necessarily is backward looking, targeted at determining whether the municipality had information prior to the unconstitutional conduct”
