When asked, David Cameron said the Johns were treated "in the appropriate way" by the court:

Asked about the recent ruling, the Prime Minister said that Christians must be “tolerant and welcoming” towards homosexuality.

His comments, made during a visit to Derby on Tuesday, came a week after the High Court ruled on the case of the Pentecostal Christian couple Eunice and Owen Johns who were told they could not be foster carers because of their view that homosexuality is wrong.

In that same judgment the two High Court judges said there was no place in British law for Christian beliefs, despite this country’s long history of religious observance and the traditions of the established Church.

Lord Justice Munby and Mr Justice Beatson backed Derby city council by ruling that homosexual rights “should take precedence” over the rights of Christians in fostering cases.

... During a visit to the area, when asked about the case Mr Cameron told reporters: “This matter was decided by a court in the appropriate way and I think we should rest with the judgment that was made.” Asked further if he thought Christian views were incompatible with an acceptance of homosexuality, he added: “I think Christians should be toler ant and welcoming and broad-minded.”

Government sources later told the Daily Mail that the Prime Minister was “not taking sides” in the debate, but his comments were criticized by Christian campaigners." (source)
