Could school districts get mask mandate court rulings overturned?

Perkiomen Valley school district in Montgomery County voted to lift its universal masking requirement.

It's a complicated story with really important local ripple effects, so we asked Villanova Law Professor Michael Moreland to help us to understand the case in question, what it means for schools and students, and what's going to happen next.
