Ruling on row over Jackson tribute show.
Nicholas Strauss QC, sitting as deputy High Court judge, said the temporary order would prevent Iambic Media from "exploiting film and sound recordings" of The Michael Jackson Forever Tribute Concert, held at the Millennium Stadium in Cardiff in October 2011.
The judge heard that a firm which financed the concert was in dispute with Iambic over copyright entitlement.
Finance firm Quickdraw claimed "all relevant rights" - an argument disputed by Iambic, the hearing in London was told.
The judge granted an injunction pending trial after concluding that the "balance of convenience" favoured Quickdraw.
Quickdraw had loaned money to event organiser Global Live Events, which was now in administration, said the judge, in a written ruling.
