Final answer:
A school group's victory in securing the right to protest at city hall pertains to Constitutional Law, specifically civil liberties, and demonstrates the judiciary's role in protecting constitutional rights.
Step-by-step explanation:
The right to protest in front of city hall involves Constitutional Law. This law pertains to the rights and freedoms guaranteed under the Constitution, including the First Amendment rights to free expression, peaceful assembly, and petitioning the government. The scenario with the school group winning the right to protest invokes these civil liberties, highlighting the constitutional protections that prevent the government from imposing viewpoint-based restrictions on public demonstrations. Given the court's decision allowing the protest, this situation demonstrates the affirmation of constitutional civil rights and the judicial system's role in upholding them.
