The seizure of documents from Newcastle United by tax officials may have been unlawful, a judge has said.
St James' Park and West Ham United's ground were raided in April by HM Revenue and Customs (HMRC) as part of an inquiry into suspected tax fraud.
The club applied for permission to seek a judicial review of the search-and-seize order HMRC had obtained.
A High Court judge said it was "arguable" on several grounds the search warrant was obtained unlawfully.
Mr Justice Supperstone, sitting in London, said there must be a full court hearing of the issues.
