ADR Experience and Qualifications
- Oversaw a complete restructuring of the court's felony case processes and procedures; this involved engaging, coordinating and negotiating with other criminal justice agencies, each with its own agenda and goals, which resulted in a more efficient and timely criminal justice system
- Recruited, organized and led a multiagency arson task force to implement a coordinated and cooperative effort among federal, state, county and municipal agencies to investigate and prosecute arson cases; this required engagement with both federal and state law enforcement authorities and their cooperation on cross-jurisdictional issues and sharing of agency resources
- Recruited, organized and led a multiagency white collar crime task force to implement a system of white collar crime investigation and prosecution in a relatively small jurisdiction that did not otherwise have resources to do so; facilitated stakeholder engagement among city councils, police departments and the county board
- Was named Prosecutor of the Year by the International Association of Credit Card Investigators for success in proposing, drafting and ensuring passage of legislation at the Minnesota legislature; this involved creating buy-in and acceptance from legislative sponsors, negotiating changes and amendments with opponents and critics, and testifying before several legislative committees; the legislation increased criminal penalties for large swindles and frauds, provided forfeiture of ill-gotten funds and permitted freezing of bank accounts to ensure restitution
- Chaired the fatality review committee, which examined individual cases of domestic homicide to identify procedures and policies across the entire court system in need of improvements; this involved getting all the agencies represented to acknowledge their own flaws and to commit to follow sometimes unwelcome recommendations for change
- Negotiated and coordinated the Minnesota Judicial Branch's change from local to state funding; during this process, the objectives and goals of urban court districts were diametrically opposed to those of the rural court districts; all aspects of court administration statewide had to be negotiated and restructured
- Assigned to, made pretrial rulings in and obtained settlements in the first Minnesota case brought under new legislation allowing the state Pollution Control Agency to directly sue insurance companies for environmental cleanup costs caused by their insureds; all challenges to the legislation were denied, and eventually all cases settled
- Assigned to and made numerous pretrial rulings in a priest sexual abuse case; one of those rulings involving the application of the statute of limitations was affirmed on appeal and eventually led to a legislative change to the statute of limitations for such cases
- Presided over a trial in which two plaintiffs suffering from multiple personality disorder alleged sexual abuse by their treating psychiatrist; during the trial, the plaintiffs—who ultimately received a $4 million verdict—were allowed to testify in one of their altered personality states after being hypnotized; there was no appeal
- Presided over a medical malpractice case in which the plaintiff died as a result of a bacterial infection following childbirth; the jury's verdict of over $20 million was the largest medical malpractice verdict ever recorded in Minnesota
- Assigned a case in which the Minnesota Pollution Control Agency sued several German automakers that employed "defeat" technology in diesel vehicles to improperly pass EPA pollution testing; ruled that portions of the case could proceed despite defendants’ previous settlement in federal court and federal preemption arguments
