Comments about "Lorentz covariance" in Wikipedia

This document contains comments about the article Lorentz covariance in Wikipedia
In the last paragraph I explain my own opinion.




The article starts with the following sentence.
2. This condition is a requirement according to the principle of relativity; i.e., all non-gravitational laws must make the same predictions for identical experiments taking place at the same spacetime event in two different inertial frames of reference.
This sentence is much to strong.
What is true for any law is the following: A law must must make the same predictions for identical experiments.
The text uses the concepts 'spacetime' and 'inertial frames'. The reason why you need different inertial frames is not explained for example when you want to study the movement of the planets.
