We show that every twisted action (α, τ) of a locally compact groupGon aC∗‐algebraAis Morita equivalent to an ordinary action ofG/Nτ, whereNτis the domain of τ. This result allows us to apply many results known for ordinary covariant systems to the more general twisted case. Especially, this is true for results which are obtained by the Mackey machine.
