In February, the order said, Allan refused during a sworn deposition to answer questions about what he and Murdoch, whose News Corporation owns the Post, talked about when the cartoon was published in 2009. Allan claimed he was protected under "editorial privilege."
But federal Magistrate Judge Ronald Ellis ruled the protection didn't apply because nothing Allan and Murdoch talked about was related to a secret source or the newsgathering process.
The Post eventually apologized for publishing a cartoon that had clearly racist imagery. It depicted a police officer shooting a chimpanzee to death and another officer saying, "They'll have to find someone else to write the next stimulus bill." It was published just a day after President Obama signed an economic stimulus package into law.
Guzman's lawyers wanted to know what Allan said to Murdoch in a series of phone calls after the cartoon ran, including whether the editor told the executive that it was a mistake to apologize.
Murdoch, however, will not have to answer questions about the cartoon. The same judge ordered on Friday that the media mogul had too little involvement in the publication of the cartoon or the alleged discrimination to be forced to submit to a deposition.
