Abstract
The hyperbolicity requiremet of a recent 16 moments model for RelativisticPolyatomic Gases is here proved for every time direction ξα. This is important because asures that the wave propagation ve- locities are finite and not higher than that of light. In addition to important mathematical consequences, this property also shows that the model respects the principle of cause and effect.
