Patricia Driscoll had been granted a protection order by a judge in Kent County Family Court in Delaware requiring her former partner Kurt Busch to stay 100 yards away from her home and place of work at all times, and that he must not make any attempts to contact her.
"The respondent shall not threaten, molest, attack, harrass or commit any other act of abuse against the Practioner," the court order is reported as saying.
Busch is further ordered to maintain a "practicable" distance from Driscoll at NASCAR events, which she frequently attends as the head of the Armed Forces Foundation where events involve US military veterans. The order acknowledges that "closer proximity is required" at events in order for Busch to "perform his duties as a driver or sponsored athlete."
Further stipulations of the order are understood to include a ban on Busch purchasing or possessing firearms and ammunition, and that he must have a psychiatric evaluation for "mental health problems related to anger control and impulse control." Full official details of the ruling by Family Court Commissioner David Jones will be released on Friday.
Driscoll applied for the order following allegations she made against Busch that he had grabbed her by the throat and slammed her head into the wall of his motorhome during a row at Dover International Speedway last September. Busch and his legal team have denied these allegations, and have responded by painting Driscoll as a vengeful jilted ex-lover out to destroy the driver's reputation.
The domestic abuse allegations have additionally been formally investigated by the Dover Police, which is a separate matter from the civil protective order issued on Monday. The office of the Delaware state district attorney has yet to announce whether the investigation has found sufficient evidence to file criminal charges against Busch.
During the protracted Family Court proceedings, Busch made some startling allegations that Driscoll - a partner in a defence surveillance firm in Washington, DC - was a "bad ass" and a trained assassin who could have overpowered him at will, adding that she had once showed up at his hotel wearing a trenchcoat and a bloody night gown. Driscoll had previously made a video for a proposed reality TV show last year called "Pocket Commando" that had portrayed her as a gun-carrying commando.
The protection order issued on Monday lasts for one year until February 16 2016, but Busch will have 30 days to appeal the order - and his attorney Rusty Hardin made it clear that they would be doing just that, and tat they had "new and previously unknown evidence from various people" to present in Busch's favour.
"Though we are not surprised by the Commissioner's ruling, in light of the restrictions on the evidence he considered, we are deeply disappointed because we believe the evidence of Ms Driscoll's total lack of believability was overwhelming," said Hardin.
"We deeply regret that Ms Driscoll has been allowed to abuse the justice system in such a flagrant way," Hardin continued, alleging that Driscoll had "clearly committed perjury" during the Family Court proceedings. "Regardless of the Commissioner's finding, we know that Kurt never committed an act of family violence.
"The evidence was un-contradicted that Ms Driscoll committed the criminal offence of trespass when she entered his motorhome at night, while he was sleeping, uninvited, without permission, and refused to leave when he repeatedly asked her to get out," Hardin added. "Mr Busch's conduct was totally reasonable and legal under the circumstances. He never intentionally, knowingly, or recklessly caused her any injury."
Since breaking up with Driscoll, Busch has started a new relationship with Ashley Van Metre, who was present last weekend at Daytona International Speedway for the first action of the 2015 NASCAR Sprint Cup Series championship.
For her part, Driscoll herself broke the news about the protection order on Twitter. She posted "From my lawyer: GOT IT!!! Order for finding of Abuse entered today Opinion with supplemental findings to be available on Friday #ThankYouGod" However, this was subsequently deleted.
"We are pleased that the court ruled in our favour," said a subsequent short formal statement from Driscoll's attorney Carolyn McNeice. "Ms Driscoll can now know that she will not receive any unwanted communications from Mr Busch and feel that she is safe after nearly 5 months."
NASCAR management and Busch's Cup team Stewart-Haas Racing both indicated on Monday that they would not be looking to suspend Busch from competition at this time, unless and until criminal charges are filed against Busch.
"NASCAR has been closely following the civil proceedings in Kent County (Del.) Family Court regarding driver Kurt Busch and therefore is aware of the court order issued today," the sanctioning body said in a statement released on Monday. "We now await the full findings of the Commissioner and any actions by the attorney general of Delaware related to the allegations against Busch.
"As we stated earlier, NASCAR fully recognises the serious nature of this specific situation and the broader issue of domestic violence. We will continue to gather information and monitor this situation very closely, and we expect our members to conduct themselves properly."
"These are serious allegations and we do not take them lightly," said Stewart-Haas Racing executive vice-president Joe Custer in a media release from the team. "We are relying on the authorities in Delaware and their collective experience to identify all the facts. They are the experts in these matters and their decision, specifically the one that will be made by the Attorney General, will determine our course of action."
Last week, team co-owner Tony Stewart told reporters that SHR had contingency plans in place for the #41 car in the event that formal charges are filed and Busch is required to step down from competition.
"We're kind of waiting to see," Stewart said. "I'm very hopeful that we won't have to worry about it. I mean, I feel bad he's in that situation right now and that they're both in that situation. But we have to be smart and we have to have a plan in place if it doesn't work out for whatever reason.
"I feel like we have to wait for the decision from up in Dover, Delaware," said Busch on Thursday. "Tony went through some tough spots, I've been through some tough spots. It's about persevering and pushing hard and believing in the people around you and having a good support system. So I feel blessed to have Stewart's situational things happen and yet the support that's been there, and Gene Haas, everybody has been wonderful.
"It's a matter of just knowing that the truth has been told, and we'll see how things unfold. The process, we have to wait on what their decision is going to be," Busch added. "Normal situations like this take 30 minutes, so we're going close to day 100, so we all have to be patient. We all have to understand that there's a process that we have to respect, and the fact that no announcement has come out, each day that goes by continues to be good news, and with the team and their support, they've been fantastic."
