Fieger has been involved with a variety of high-profile or controversial cases. In 1994, he represented
Jack Kevorkian in the first of several doctor-assisted suicide trials. Kevorkian was acquitted in that trial and all subsequent trials where Fieger represented him.

You Don't Know Jack'', aired on HBO, in which Fieger was portrayed by actor
Danny Huston. Other notable clients and cases include: • The family of
Scott Amedure in a 1999
wrongful death and negligence suit against
The Jenny Jones Show. Fieger was unsuccessful in his representation, with the
Michigan Court of Appeals holding that
The Jenny Jones Show was not liable for Amedure's death. • The family of Isaiah Shoels, who was killed in the
Columbine High School massacre. • Ralf Panitz, accused of killing his ex-wife Nancy Campbell-Panitz in July 2000, following their appearance along with Panitz's new wife, on a segment of

A&E reality show
The First 48. • A lawsuit against the
Michigan State Police on behalf of the family of 64-year-old Jacqueline Nichols, a pedestrian who was killed when a cruiser crashed into her during a police chase in
Flint on July 3, 2014. The state agreed to settle the suit for $7.7 million. • A $100 million class action lawsuit in regards to the 2014–2015
Legionnaires' disease outbreak in the
Flint, Michigan, area, on behalf of four Genesee County residents who contracted the water borne illness during the
Flint water crisis, including one woman who died seven days after entering the emergency room with a headache. The suit names
McLaren Regional Medical Center in Flint and several
Michigan Department of Environmental Quality officials as defendants. • The family of
Kenneka Jenkins, a 19-year-old girl who was found dead in a
Rosemont, Illinois, hotel freezer in 2017 after a night of partying. • A $100 million lawsuit in regards to the

Oxford Community Schools on behalf of a 17-year-old student who was shot in the neck and her sister who was walking next to her as she was shot. The suit claims that the girls are experiencing PTSD and that the school failed to protect the students by allowing the shooter to return to class after they had direct information that he was exhibiting homicidal ideation. ==Political career==
