Final answer:
Burdine v. Johnson was a legal case involving dress code regulations in schools and students' freedom of expression.
Step-by-step explanation:
Burdine v. Johnson was a legal case that illustrated the issue of dress code regulations in schools and the balance between students' freedom of expression and school administrators' authority to enforce dress code policies. In this case, two students were told that their purses displaying Confederate flags violated the dress code, and they were asked to either have someone pick up their purses or leave them in the office to stay in school. The case involved multiple appeals, eventually reaching the Fifth Circuit Court of Appeals.
