It is outlined the relevance for Quantum Gravity of inferring a kinematical SU(2) gauge structure in a generic Lorentz frame. Then, the analysis of Hamiltonian constraints is performed in vacuum and in presence of matter fields. SU(2) Gauss constraints are shown to arise even though no restriction of the local Lorentz frame takes place.
