The Kardashians are challenging the basis of Blac Chyna’s lawsuit against them and asking a judge to toss her case.

Kris Jenner, Kim Kardashian West and Rob Kardashian’s attorneys filed a “demurrer” objecting to and asking for a dismissal of Chyna’s lawsuit against them, in which the mother of two claimed the Kardashians were responsible for E! not moving forward with the planned second season of Rob & Chyna, the former couple’s reality show documenting the birth of their 1-year-old daughter Dream Kardashian.

In the documents filed Dec. 21, the Kardashians allege Chyna, 29, herself prevented the show from filming after receiving a domestic violence restraining order against Rob, 30, in July.

The order prevented Rob from contacting Chyna “either directly or indirectly, in any way” and required him to stay away from her, her home and place of work.

According to the filing, “Given Plaintiff’s conduct in seeking and obtaining a restraining order that required Rob to stay away from Plaintiff and her workplace, no trier of fact could possibly find that it was reasonably probable that a second season of Rob & Chyna would have been picked up and filmed.”

The filing also states that Jenner, 62, and Kardashian West, 37, have a court date Jan. 18 in Los Angeles to present their case for having the lawsuit dropped.

In October, Chyna filed the lawsuit against her ex-fiancé for allegedly damaging her brand and verbally and physically abusing her, which he denied.

The complaint, which asked for unspecified damages, also named Kris Jenner and all of his sisters Kourtney Kardashian, Kim Kardashian West, Khloé Kardashian, Kendall Jenner and Kylie Jenner. The lawsuit was later amended to name only Jenner and Kardashian West, as well as Rob.
