The laws of electromagnetism apply to all IRFs.
Maxwell's equations do not.
Therefore, Maxwell's equations are not laws of physics.

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 true. Regardless of the origin, "Maxwell's equations" is the
Common Language name of that set of equations.
 Heaviside got the equations from Maxwell. Heaviside just identified the
most important equations among all that Maxwell had presented. In addition
Heaviside invented vectors and demonstrated that using vectors those (and
other) equations could be written in a simpler form.

Well, that's what you think.
For me it seems, that Heaviside and Gibbs were 'con-artists' and wanted to divert physics from true science.
