A Kerala nun, who has challenged the Franciscan Clarist Congregation's decision to expel her, has written to the Vatican, alleging the 'disciplinary action' was taken for participating in protests by a group of nuns seeking arrest of a bishop accused of raping a fellow nun. In her letter to Leonardo Cardinal Sandri, Prefect, Congregation for the Oriental Churches, Sister Lucy Kalappura also sought an opportunity to her to appear in person before a tribunal which would consider her appeal against the Congregation's decision. She has also sought an opportunity to present her case to the Pope Francis.
