But at a hearing on Dec. 30, the hospital said that the patient's condition had not changed and the judge rejected suggestions that RS should be moved to Poland.
Government officials had sought to intervene amid a mounting outcry about the case in Poland. Proposals included giving RS a diplomatic passport, removing him from the jurisdiction of U.K. courts.
There were also legal moves in Warsaw aimed at paving the way for RS to be brought to the country.
The case also raised alarm among Catholic bioethicists and bishops.
The Anscombe Bioethics Centre in Oxford issued a press release and briefing paper on Jan. 12 raising concerns about the moral reasoning of the judges in the case.
David Albert Jones, the center's director, said that the judgment set "a very worrying precedent."
"The grave danger of this judgment is that committed Catholics and those who hold a similar view about the human significance of food and drink may be starved and dehydrated to death against their will," he wrote.
Two days later, Bishop Mark O'Toole of Plymouth, the patient's local bishop, also described the ruling as "very worrying."
"My prayers are with the patient, his wife and family, and for all those involved in his care. The decision of the court to allow for the withdrawal of hydration and nutrition is very worrying. That it is deemed to be in the best interests of the patient more so," he said in a Jan. 14 statement.
"Providing food and water to very sick patients -- even if by artificial means -- is a basic level of care. This is care that we must strive to give whenever possible."
Archbishop Stanisław Gądecki, president of the Polish bishops' conference, wrote to his English counterpart Cardinal Vincent Nichols on Jan. 19, asking him "to undertake steps towards saving the life of our compatriot."

In his letter, Gądecki said that public opinion in Poland had been "shaken" by the case.
"In fact, he was sentenced to death by starvation," the archbishop said.
English Catholic bishops raised the Polish Church leader's concerns with Britain's Health Secretary the following day.
"The Catholic Church continues to oppose the definition of assisted nutrition and hydration as medical treatment which has now become the basis of medical and legal decisions to withdraw assisted nutrition and hydration from patients," wrote the bishops in their Jan. 20 letter to Health Secretary Matt Hancock.
"Providing food and water to very sick patients, even by assisted means, is a basic level of care. This care must be given whenever possible unless it is medically indicated as being overly burdensome or failing to attain its purpose."
The letter was signed by Bishop John Sherrington, an auxiliary bishop of Westminster with responsibility for life issues at the English and Welsh bishops' conference, and Bishop O'Toole.
