Green later said that it had been one of the most difficult decisions of his career but was based on principled support for the death penalty, which was inconsistent with the Constitution.
[6] Green was also an opponent of equal rights for gay people: when Njongonkulu Ndungane, the Anglican Archbishop of Cape Town, congratulated Gene Robinson on his consecration, Green reminded Ndungane that homosexuality was "an abomination" in terms of Leviticus and said that "as Christians we cannot interpret God's word to suit modern lifestyles".
He was suspended from the committee in October 2003, apparently for breaching its confidentiality rules, though Green disputed that he had shared any confidential information: during the committee's inquiry into Deputy President Jacob Zuma's financial interests, Green had told the media that Zuma's defence relied for evidence on loan documents that were "only recently drawn up".
[8][9] On 1 September 2005, during that month's floor-crossing window, Green resigned from the ACDP and defected to the newly established FD.
[3][5] He later said that he had left "on a matter of principle" because he disagreed with how Meshoe had treated Rhoda Southgate, the ACDP parliamentarian who founded the FD.
