Are Maxwell's equations Lorentz-covariant?

“…That is, do Maxwell's equations retain their form and content under transformation of variables (5)? The correct answer appears to be: the Maxwell equations are ready-made to be Lorentz-covariant, but they are actually Lorentz-covariant only if we construct to be so (cf, e.g., [12,13]). As was demonstrated above, what exactly is sufficient to be postulated for the covariance emanates from the equations themselves.…”
