[citation needed] An expert in Conservative approaches to, and interpretations of, the halakhah, Roth was appointed to the Committee on Jewish Law and Standards in 1978, and served as chairman for eight years.
Many of his responsa for the CJLS have been published in a number of collections by the Rabbinical Assembly and the United Synagogue of Conservative Judaism.
In addition to articles and responsa for the committee, Roth has written The Halakhic Process: A Systemic Analysis and Sefer ha-Mordecai: Tractate Kiddushin.
On December 6, 2006, Roth resigned from the Committee on Jewish Law and Standards after the acceptance of a paper by Rabbis Elliot Dorff, Daniel Nevins and Avram Reisner on homosexual relationships and ordination of homosexual rabbis, while it upheld the biblical prohibition on male intercourse.
[1] The committee also adopted Roth's own, diametrically opposed responsum, maintaining a complete prohibition on homosexual conduct.
