In a sensational move on Tuesday, the former reality television mother dismissed the suit with prejudice against her husband of 10 years, barring her from bringing an action on the same claim.
Dismissal with prejudice is considered a final judgment.
He is alleged to have illegally tapped and accessed Kate's computer without her authorization.
"Plaintiff Kate Gosselin agrees to dismiss with prejudice all claims and potential claims that she has or may have against Defendant Jonathan K. Gosselin that were or could have been asserted in this case,” a motion filed in the United States District Court of Pennsylvania on Tuesday afternoon said.
"By this motion, Plaintiff Kate Gosselin is not dismissing her claims against any Defendant other than Defendant Jonathan K. Gosselin.
"Defendant Jonathan K. Gosselin agrees to dismiss with prejudice all counterclaims or potential counterclaims that he has or may have against Plaintiff Kate Gosselin that were or could have been asserted in this case.”
RadarOnline.com broke the story: In August, Kate filed a sensational lawsuit against her ex-husband accusing him of wiretapping, computer hacking, identity theft and invasion of privacy.
“After the couple was separated, Jon illegally hacked into Kate’s email account and her phone and bank accounts,” the suit initially alleged.
“Jon also stole a hard drive from Kate’s house, which contained private and confidential material. Jon the gave them the contents of Kate’s email account and the hard drive, all of which were acquired illegality, to his friend and business partner, tabloid reporter Robert Hoffman.
“Hoffman used the illegally acquired data to publish a defamatory book about Kate … the book was removed from large distributors like Amazon.com because the information was obtained illegally.
“Nevertheless, the damage was done with the release of the personal and private information and the defendants continue to possess this illegally obtained private information.”
Kate said Hoffman, at one point, even ”bragged” that he was in possession of 5000 family photos, personal documents, tax and business records, plus contracts.
In the filing, Kate said Hoffman falsely claimed that he recovered the data from her computer by digging through her trash that he found on the street.
“This demonstrates his knowledge that the materials were obtained illegally, as it is a sign of an attempt to cover up his unlawful activities,” the suit alleges.
“The materials in his possession could not possibly be physically found in paper format to that extend. If Hoffman was picking through trash on the street, he did not find this trove of personal information while engaging in his trash-picking endeavors.”
