Connells brand Gascoigne Halman has won the right to appeal in the OnTheMarket case.
The appeal follows the hearing in February at the Competition Appeal Tribunal, which subsequently upheld OnTheMarket’s ‘one other portal’ rule.
Gascoigne Halman has continued to list its properties at OnTheMarket.
Today’s written judgement was made by Lord Justice Kitchin in the Court of Appeal’s civil division.
He said that he had been “persuaded that the grounds of appeal as developed in the appellant’s skeleton argument are properly argued and merit consideration by this court”.
He said that the hearing will decide whether it is “appropriate to receive the fresh evidence”.
OnTheMarket – which has been finalising plans to float on the stock market – said it would not be commenting.
Connells also said it would not be commenting.
