John Marshall alumna Susann "Sunny" MacLachlan is a Clinical Professor and Director of the Center for Advocacy and Dispute Resolution.
The 1994 cum laude graduate competed in the National Products Liability Competition taking third place nationally and second place best brief nationally. MacLachlan also was a member of the ABA Criminal Justice Trial Advocacy Team in 1993, and the Regional Negotiations Team in 1993. MacLachlan also was a Dean's Scholar, a member of the Order of John Marshall, the 1994 recipient of The John Marshall Law School Award for Public Service, and the 1992 Ewing Fellowship of Alpha Chi Omega for Academic Achievement in Law. She was the student representative to the Chicago Inn of Court, a membership she still holds. After graduating from John Marshall, MacLachlan was an Assistant Corporation Counsel for eight years, prosecuting criminal misdemeanors and Chicago ordinance violations in the Municipal Prosecutions Division of the City's Law Department.
She also assisted in the implementation of the federally funded Drug and Gang House Enforcement Section pilot program. In the DGHES unit, MacLachlan worked closely with the Chicago Police Department in investigating and prosecuting Chicago property owners and managers who permitted illegal gang or narcotics activity to occur on their property. As a result of her efforts, MacLachlan was invited to present on this topic at international municipal attorneys conferences.
MacLachlan was later promoted to senior trial supervisor for the Mayor's License Commission, overseeing a staff of 16 attorneys, law clerks, and support staff. In this capacity MacLachlan investigated and prosecuted narcotic and other vice-related violations of state statute and municipal ordinance under the Liquor Control Act, resulting in the revocation of liquor and other business-related licenses issued by the City of Chicago. This position also involved extensive client counseling, trial training of junior attorneys and law clerks, trial and negotiation strategies, and the overseeing of all litigation handled by the unit.
MacLachlan currently teaches a popular Animal Law course, is the faculty advisor to the Animal Law Society (SALDF), and has coached John Marshall teams to five first-place awards in the last four years at the Animal Advocacy Closing Argument Competition at Harvard Law School. MacLachlan also teaches International Negotiation and Mediation, Trial Advocacy, and oversees the school's new LLM in Trial Advocacy and Dispute Resolution program. She is also a member of the Board of Directors for the Animal Legal Defense Fund.
