About John Justin
John Justin Hansen is an attorney admitted to practice in Illinois and Wisconsin and is also admitted to the United States Court of Appeals for the Seventh Circuit. He works at Gruber Law Offices and appears in state and federal forums across the region. He handles matters that range from trial-level litigation to appellate proceedings before the Seventh Circuit.
Hansen’s practice spans the two Midwestern states where he holds admission. He regularly files briefs and appears on motions in Illinois and Wisconsin courts. He also prepares appellate briefs and participates in oral argument when cases reach the federal appellate level. His admission to the Seventh Circuit allows him to carry matters beyond the trial court and into the appellate process.
Colleagues describe Hansen as methodical in the courtroom. He approaches litigation by breaking complex problems into discrete issues, then addressing those issues through targeted pleadings and motions. At the appellate stage he focuses on clear, concise briefing and careful preservation of the record. That combination of trial and appellate work means he often follows a client’s case from early filings through post-trial work and, where necessary, into appeals.
Hansen’s work requires close attention to procedure and timing. He spends considerable time on pretrial preparation, discovery strategy, and drafting dispositive motions. When cases proceed to trial, he performs witness preparation and examines factual records with an eye toward how those issues will be presented on appeal. In appellate matters, he emphasizes written advocacy and the precise application of legal standards under established precedent.
Outside court, Hansen engages in the drafting and review of pleadings and legal memoranda that undergird trial and appellate strategy. He consults with clients on litigation risk and procedural options available in both Illinois and Wisconsin systems. His practice at Gruber Law Offices involves representing clients in multi-jurisdictional disputes and managing the procedural steps needed to keep those matters moving.
He is currently practicing at Gruber Law Offices, representing clients in state and federal courts in Illinois and Wisconsin and in proceedings before the United States Court of Appeals for the Seventh Circuit.
