Baron Moynihan, of Leeds in the County of York,[1] is a title in the Peerage of the United Kingdom.

[2][3] The titles fell into a six-year period of dormancy while they were the subject of a dispute on the death of his grandson, the third Baron, in 1991.

[5] After this action had been decided, the Committee of Privileges of the House of Lords ordered DNA testing of Andrew Moynihan, which found that the third Baron was not his father.

In the case of the elder, Andrew, the committee was shown overwhelming genetic evidence that he cannot be the son of the late Lord Moynihan; and so far as the younger, Daniel, is concerned, the evidence clearly shows that he is the child of a bigamous marriage and is therefore illegitimate.

In those circumstances, it is clear beyond doubt that the petitioner, Colin Moynihan, must be the rightful heir and that his Petitions must succeed.
