Defendant Files Removal Notice
Dorothy Daniels sued a supplier in state court for breach of contract. The supplier filed a notice of removal in the district court for the district where the state action was pending, attaching all served process and pleadings along with a short statement of diversity grounds. The district court accepted the filing and the case proceeded in federal court.
Court Excludes Expert Testimony
Dustin Donovan offered an expert opinion linking a chemical exposure to his illness. The district court found too great an analytical gap between the data and the proffered conclusion and excluded the testimony. On appeal the circuit court reviewed that gatekeeping decision only for abuse of discretion.

Daphne Doyle sought to introduce a business record in a contract dispute pending before a United States district court. The court applied the Federal Rules of Evidence to determine admissibility because those rules govern all proceedings in district courts.
Transfer Despite No Jurisdiction
Deanna Davenport sued a defendant in a district court that lacked personal jurisdiction over him. Rather than dismiss, the district court transferred the action under section 1406(a) to a district where the action could have been brought, preserving the case in the interest of justice.
Court Bars Prior Conviction Evidence
Dylan Duffy was charged as a felon in possession and offered to stipulate to his status. The district court excluded the full record of the prior conviction under Rule 403 because its probative value was substantially outweighed by the danger of unfair prejudice.
Overloaded Dockets Affect Process
Devon Drake's civil rights case reached the district court amid a heavy caseload. The court noted that overloaded dockets force greater delegation to magistrates and reduce time for reflection, illustrating the systemic pressures on district courts described in the opinion.
