Trevor Hicks, who lost both daughters in the Hillsborough disaster, said the victims' families were "delighted" with today's ruling and added that "justice is on its way".
Outside the High Court, Mr Hicks added that today was a "huge step for the families".
The Hillsborough inquest verdicts of accidental death have been quashed by the High Court and a new police investigation has been announced.
Families of the Hillsborough victims are on their way to London for a historic hearing. They hope to hear the inquest verdicts overturned.
