Granting a restraining order has very, very little to do with the judge's evaluation of the evidence. It has everything to do with someone filling out a form, making allegations that fall within certain parameters and then a respondent who chooses either to challenge or not to challenge the restraining order.
My example? In 2005, a judge in New Mexico granted a temporary restraining to a woman who alleged she needed protection from David Letterman. She alleged he was using code words, gestures and eye movements in an attempt to persuade her to marry him.
Do you think that judge REALLY believed that David Letterman was doing any of those things? I don't. But I believe that the judge followed the law in granting the temporary restraining order.
Had David Letterman chosen not to challenge that temporary order, it would have remained in force for something like a year. Would that have made the allegations true? I doubt it.
David Letterman did choose to challenge the temporary order and it was stricken down within days.

KH chose to petition for a temporary restraining order. It wasn't the job of the judge to decide whether the allegations were likely to be true or not. All the judge does is evaluate the petition to make sure that it fulfils the provisions of the law in Oregon and whether the remedies asked for also fall within the scope of the law.
It was up to TMH to choose whether to challenge that petition or not. Had she chosen to challenge, there would have been a "show-cause hearing" at which KH would have had to show actual evidence to support his allegations.
TMH chose not to challenge the restraining order. What that means is up to the individual to decide.
