375.This section sets out the process by which the Authority can object under section 187 to an existing controller. If the Authority wishes to object to a controller, it is obliged to give him a warning notice.
376.Subsection (2) has the effect that the Authority must comply with any requirements prescribed by the Treasury with respect to the consultation of other competent authorities outside the UK before it gives a warning notice.  The Treasury will exercise this power to ensure that effect is given to requirements imposed by the single market directives to consult home State competent authorities.
