Pat Houston, the sister in-law of the legendary singer Whitney Houston, won a small victory in court earlier this week.

Houston filed a restraining order against Bobbi Kristina‘s brother/hubby Nick Gordon last month after Gordon posted a slew of online threats against she and her family (click HERE if you missed that).

Well… now that the 30 day window has passed, a judge has ordered Nick to stay away from his wife’s family for the next full year!

[Sidebar: That can’t be good news for Nick if he was planning to attend the Houston’s Easter dinner… ]

Details below…

According to TMZ:

Whitney Houston’s sister-in-law just got a year’s worth of peace of mind … a judge has just ordered Whitney’s son-in-law Nick Gordon to stay clear of her for the next year.

We broke the story … Pat Houston got a restraining order against Nick last month … claiming he made threatening comments against her and posted ominous photos of guns on Twitter.

Now a judge has extended the order for 12 months, so Nick can’t contact Pat or anyone in her immediate family … he comes within 200 yards — he goes to jail.

The bad blood is long-standing. Family members tell us Nick resents Pat because she controls the purse strings of Whitney’s estate … and he thinks his wife Bobbi Kristina got screwed on her inheritance.

We reached out for comment … so far, no response.

Welp… one thing’s for sure. If Nick acts up online or off, Pat’s gonna have him locked up. ?This should make for interesting conversation during the Houston family functions…

What do you think of this ongoing Houston Family Feud?
