The laws of electromagnetism apply to all IRFs.
Maxwell's equations do not.
Therefore, Maxwell's equations are not laws of physics.
 "AI Overview
Maxwell's Equations in Electromagnetism - GeeksforGeeks
Yes, Maxwell's equations are considered laws of physics. They are a set
of four fundamental equations that describe the behavior of electric and
magnetic fields, and how they are generated and influenced by charges
and currents. These equations are foundational to classical
electromagnetism and are used in various technologies like power
generation, electric motors, and wireless communication."
 

Actually this isn't true, because those four equations didn't stem from Maxwell, but from Oliver Heaviside.
It is really important, that Maxwell himself was an 'aetherist' and wanted to use quaternions.
Maxwell himself wrote 20 quaternion equations, which were crippled to the current four equations by Gibbs and Heaviside.
