摘要：

We reconsider the problem of finding all local symmetries of a Lagrangian. Out approach is completely Hamiltonian without any reference to the associated action. We show that the restrictions on the gauge parameters entering in the definition of the generator of gauge transformations follow from the commutativity of a general gauge variation with the time derivative operation.
