The state's highest court is expected to hear arguments in two separate cases involving guns in schools on Wednesday.
The state supreme court will hear a case involving Ann Arbor Public Schools and the Clio Area School District.
Both are facing lawsuits filed by gun rights groups after banning weapons on school grounds.
Back in 1996, the Clio Area School District enacted a policy banning weapons on school property.
In March of 2015 Kenneth Herman filed a lawsuit against the district over its gun ban.
Court documents show despite having a concealed pistol license, he was denied access to school property several times in 2013 and 2014 while openly carrying a pistol.
His daughter attended Clio Elementary at the time.
A similar thing happened to Josh Wade, who openly carried a gun at his sister's choir concert at Pioneer High School in Ann Arbor.
Wade was able to stay because state law allows people with a CPL to carry firearms in gun-free zones but they're not allowed to conceal them.
Shortly after that, Ann Arbor Public Schools unanimously voted to ban all guns on school property and at school events.
After that, Michigan Gun Owners Incorporated filed a lawsuit against the district over the rule change, arguing a local school board does not have more authority than state legislature.
In both cases -- the State Court of Appeals upheld lower court rulings in favor of Ann Arbor Public Schools and Clio Area School District.
Wednesday, the state supreme court will reopen those cases together and could shape the future of gun control in Michigan schools.
Court begins at noon and you can watch it here.
