Letters of complaint to the JCIO said that Ms Hassell had made unsubstantiated allegations in her letter.
The JCIO said that after a detailed investigation, the Lord Chancellor and the Lord Chief Justice were ”satisfied that Coroner Hassell had not misrepresented or distorted the position in her letter as alleged and have dismissed this aspect of the complaint”.
But it found that her disclosure of a private letter amounted to misconduct.
Rabbi Asher Gratt, of the Adath Yisroel Burial Society, said that the reprimand “ought to be a signal that it is time for her to step down or at the very least to be moved to an area where she might cause less controversy.”
Rabbi Gratt said the dismissal of the complaint that the letter had misrepresented facts was likely to be appealed.
