Explanation:

Mary Beth Tinker in December, 1965, made a decision  to wear black armbands to her school Des Moines Independent Community School District, Iowa, as a protest to the America's involvement in Vietnam War because of that, the school management made a plan to suspend any student caught wearing armbands as a sign of protest. Some  students disobeyed and arrived the school with black armbands refusing to remove the hand bands and were suspended along side Mary Beth

The 1969 Supreme Court delegated on the  case of Tinker v.
