We propose a short summary of the present situation concerning the proton spin decomposition. We discuss some of the main controversies about the issues of gauge invariance, Lorentz covariance, uniqueness, physical interpretation and measurability. As a conclusion, we argue that part of the controversies is actually undecidable.
