A German court has ruled that public broadcaster ZDF can’t be forced to post a specifically worded apology demanded by a Polish court for erroneously calling two World War II Nazi camps “Polish death camps.”

ZDF used that wording in reference to the Majdanek and Auschwitz death camps in advertising a 2013 documentary. After the Polish Embassy in Berlin objected, it changed the text to “German death camps on Polish territory.”

A Polish citizen who was a former inmate of Auschwitz and the Flossenbuerg concentration camp then launched a legal battle with ZDF, which twice apologized to him for the initial error and later published an apology.

In 2016, the plaintiff secured a ruling from a court in Krakow, Poland, ordering ZDF to post on its website for one month an apology stating that the original wording was “an incorrect formulation that distorts the history of the Polish people.” The broadcaster did publish the text from Dec. 2016 to Jan. 2017, but the plaintiff considered its compliance unsatisfactory and sought to have the Polish ruling legally enforced.

Lower German courts ruled that the verdict can be enforced in Germany. But the Federal Court of Justice said that it disagreed because the required formulation would violate the broadcaster’s right to freedom of opinion.

The father of two young girls found submerged in oil tanks after being missing for days told authorities his pregnant wife killed the children after learning he wanted a separation, and that he erupted in rage after witnessing the killings and strangled their mother inside the family's suburban Denver home, according to court documents.

Days after letting police inside his home so they could help find his missing family, Christopher Watts told investigators "he would tell the truth."

Watts first asked to speak with his father then admitted to killing his wife, Shanann. Watts told police in court papers released Monday that he killed her after witnessing her strangling one of the girls on a baby monitor. The other child had already been killed by the woman, he said.

Watts, 33, faces three first-degree murder charges, two counts of murdering a child under 12, one count of unlawful termination of a pregnancy and three counts of tampering with a deceased human body. He is scheduled to appear in court on Tuesday and is being held without bail.

District Attorney Michael Rourke declined to answer questions about the case Monday but said his office has three prosecutors working on it. Rourke also said it was too early to discuss whether he will seek the death penalty.

Police first visited the family's house on Aug. 13, after a friend asked officers to check on Shanann Watts. She had missed a doctor's appointment and wasn't answering calls or text messages hours after returning home after a business trip, the friend reported.
