The court ruling now means that Rooney must prove that Vardy herself was responsible for the allegations against her account if she is to defend the libel case brought against her.
However, the pair's lawyers have agreed to meet for one final attempt to resolve the case outside of court, with a stay in place until February 8.
During their court hearing this week - which took place without Vardy or Rooney attending in person - lawyers for Vardy argued that Rooney's "detective process" in her Instagram post was "to find the true villain of the piece", and claimed "the finger is being pointed" at Vardy as a person, rather than her Instagram account.
Hugh Tomlinson QC, for Vardy, said: "The person is Rebekah Vardy, the finger is being pointed at her, as the villain, the person, the someone, the one person."
However, court documents claim Rooney only ever accused Vardy's account of accessing the stories, not the star herself.
They state: "The source of the leaks of the Defendant's private information was the Claimant's account.
"The emphasis of 'except ONE account' (with capital letters) and the final words of the post make clear that the responsibility lies with a particular account.
"As a result of this, a reasonable reader would conclude that there were reasonable grounds to suspect that the Claimant had leaked the information herself, but the finger is pointed firmly at the account, not the Claimant herself."
