Ulman is the Rabbi of Friends of Refugees of Eastern Europe (FREE), which has been servicing Sydney's Russian-speaking community since 1986.
The Rabbinical Council of NSW, of which Ulman was a vice president at the time, issued a ruling that forbade any dispute with a Jewish institution from going to the courts, unless mediation had failed.
The ruling included an excommunication order that called on the community to "expel his children from school and his wife from synagogue".
"[9][10] Ulman was also involved in the siruv (Jewish contempt of court order) of South Caulfield Hebrew Congregation in Melbourne.
The dispute began when the congregation reduced the salary of their existing rabbi and member of the Melbourne Beth Din, Yacov Barber.
"[17] In March 2019 the NSW Jewish Board of Deputies (JBOD) intended to investigate the Beth Din which Ulman is a part owner and senior member.
JBOD said that the Beth Din had a "history of effectively undermining the theological basis of Orthodoxy and halachah," and that there were serious "defects in the ownership structure, governance, mechanisms of accountability and dispute-resolution processes" and that they were a law unto themselves.
[21] Ulman supplied written testimony to court on behalf of Jaron Chester, who was accused of money laundering for an alleged Sydney organised crime family.
[25] In a submission to the Senate inquiry into same sex marriage, to which Ulman was a signatory, homosexuality was compared to adultery, incest and bestiality.
