Hey there! I'm happy to help!
Goss vs. Lopez was a Supreme Court Case that said that a student cannot be suspended from school without a notice and hearing.
What happened is that 9 students in the Columbus School District in Ohio were suspended for misconduct and they weren't given a notice or a hearing of some sort. So, they, led by the student Dwight Lopez filed a lawsuit against the school district, represented by Norval Goss, head of the department of pupil personnel.
The Supreme Court ruled in favor of Lopez and stated that what the principals in the school district were doing was unconstitutional and infringed on the 14th amendment due process rights of the students, so they would have to be allowed a notice and a hearing before suspension.
Have a wonderful day and keep on learning! :D
