How Judge Guzmán decides
Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.
What persuades
On a res judicata / claim-preclusion defense he demands a genuine final judgment on the merits by a court of competent jurisdiction, and he applies Illinois preclusion law precisely: an unreviewed IHRC administrative decision gets no preclusive effect in federal court, and an Illinois dismissal for want of prosecution is NOT an adjudication on the merits (distinguishing federal Rule 41(b)). He will not build the moving party's preclusion argument for it.
“the Court has no basis on which to conclude that Plaintiff’s IDHR complaint and subsequent proceedings preclude her claims here.”
On a Lanham Act trade-dress claim he requires the asserted trade dress to be described in concrete, specific detail — stripping out conclusory adjectives — so the court and defendant can identify the distinctive, non-functional features; labels like 'unique' and 'recognizable' do not state a claim. Photographs are not required but detailed feature descriptions are.
“Simply using conclusory words like ‘unique’ and ‘recognizable’ does not make it so.”
In employment cases he applies the Seventh Circuit's materially-adverse-action requirement: a written warning (or a Hatch Act warning letter) is not an adverse employment action, and a claim already fully litigated through an administrative tribunal and affirmed on appeal is barred by res judicata. Unexhausted Title VII theories are dismissed.
“A written warning, however, does not constitute an adverse action.”
Procedural preferences
He is solicitous of pro se litigants' procedural footing: he construed a pro se plaintiff's misfiled factual allegations as part of her complaint, granted leave to amend to consolidate them, and (on the other side) confirmed the required pro se LR 56.1 'Notice to Pro Se Litigant' had been served before treating unopposed summary-judgment facts as admitted.
“the Court grants leave for Plaintiff to file the proposed second amended complaint in full.”
Cautions
He enforces the PLRA exhaustion requirement strictly against prisoner plaintiffs: a detainee who did not appeal a disciplinary conviction or file a grievance cannot have the merits of the resulting due-process claims considered, and an unopposed, LR 56.1-noticed summary-judgment motion will have its facts deemed admitted.
“Because the record establishes that plaintiff did not exhaust administrative remedies, the Court cannot consider the merits of his due process claims.”

Caseload & timing
From public federal docket records for this judge.
Median case duration in the sampled dockets: 42.5 days (N = 10).
Median motion-to-ruling time: 50.5 days (N = 2).
The reviewed 2023 filing cohort, drawn during Judge Guzmán's senior service, includes immigration-delay suits, personal-injury and pharmaceutical-product cases, consumer-debt disputes, employee-benefit collection actions, and commercial and contract matters. The observed durations are unusually short and include stipulated or administrative terminations and possible reassignments rather than only contested merits decisions.
