Abstract: We prove here that the localisation principle holds for anisotropic quadratic spaces over $ R[T,{T^{ - 1}}]$, where $ R$ is an integral domain in which 2 is invertible. We also give an example of an isotropic quadratic space over $ R[T,{T^{ - 1}}]$ for which the localisation principle does not hold.
