After Brexit, the UK will operate its own system of trade remedies. The essential scheme of the new regime is that a new Trade Remedies Authority will act as the gatekeeper, investigator and first-line decision-maker, while the secretary of state will have general powers of supervision and the ability to block any proposal to impose a trade remedy on broad public interest grounds. Those who wish to challenge the TRA’s or the secretary of state’s decision must do so by way of judicial review application to the Upper Tribunal. The operation of the new trade remedies regime is going to provide significant challenges both for the TRA and for advisers to both UK companies seeking trade remedies and importers and foreign governments seeking to contest them.
