Abstract: We study the structure of the phase space in Ho\v{r}ava-Lifshitz theory. Withthe constraints derived from the action, the phase space is described by fivefields, thus there is a lack of canonical structure. The Poisson brackets ofthe Hamiltonian density do not form a closed structure, resulting in many newconstraints. Taking these new constraints into account, it appears that thereis no degree of freedom left, or the phase space is reduced to one with an oddnumber of fields.
