Article 23U.K.
1.Where the refund application is refused in whole or in part, the grounds for refusal shall be notified by the Member State of refund to the applicant together with the decision.
2.Appeals against decisions to refuse a refund application may be made by the applicant to the competent authorities of the Member State of refund in the forms and within the time limits laid down for appeals in the case of refund applications from persons who are established in that Member State.
If, under the law of the Member State of refund, failure to take a decision on a refund application within the time limits specified in this Directive is not regarded either as approval or as refusal, any administrative or judicial procedures which are available in that situation to taxable persons established in that Member State shall be equally available to the applicant. If no such procedures are available, failure to take a decision on a refund application within these time limits shall mean that the application is deemed to be rejected.
