In addition to Mr. Redstone’s testimony, the judge said he was also strongly influenced by Dr. Read’s acknowledgment under cross-examination that Ms. Herzer at this point would not be a viable choice for management of Mr. Redstone’s current or future care.

In his testimony, videotaped on Thursday, Mr. Redstone said that he hated Ms. Herzer. In response to a question about whether he wanted Ms. Herzer to make health care decisions for him, Mr. Redstone replied, “No.”

“I want Manuela out of my life,” Mr. Redstone said at the end of the session when his lawyer asked what he wanted at the end of the trial. The videotaped testimony was shown after reporters and spectators were cleared from the courtroom and a transcript was provided to news organizations afterward.

In response to a question from his lawyer about who he wants to make his health care decisions if he is unable to do so himself, he responded with the name of his daughter: “Shar — Shari.” He also confirmed that he had been seeing his family lately and was happy with the nursing care that he was receiving.

While Ms. Herzer claims that she is concerned about Mr. Redstone’s well-being, his lawyers say that she is after his money. On the same day Ms. Herzer was removed from the health care directive, she was also removed from Mr. Redstone’s estate plan, in which he had planned to give her $50 million and his $20 million Los Angeles mansion.

In his testimony, Mr. Redstone was able to answer some questions — especially those with yes or no answers — but did not respond to others. When asked what his birth name had been, for instance, he remained silent. (It is Sumner Murray Rothstein.) The transcript shows that the flow of the testimony was sporadic, and at one point his interpreter asked that Mr. Redstone’s dentures be adjusted in order to better understand him.
