Changes are not made for their own sake, but rather to deal with an urgent, acute problem, with a preference for lenient ruling over strict ones. This is because there is generally more readiness to change a new law or something which is only a custom. Note that Conservative Judaism does not view the Shulkhan Arukh as the ultimate authority in matters of Jewish law and custom. It is composed of 25 rabbis, who are voting members, and five laypeople, who do not vote, but participate fully in deliberations. When any six members vote in favor of a position, that position becomes a validated position of the committee, thus there is the possibility that any issue can generate from one to four official positions.
Unanimous decisions become the official position of the Conservative movement.
In the overwhelming majority of cases, Conservative rabbis choose among the law committee's validated positions. On rare occasions, an individual rabbi may ignore the committee and act in accordance with his or her own convictions regarding what is halakhically correct. CJLS decisions are not absolutely enforceable on rabbis, except regarding 'standards'. A complete prohibition on rabbis and cantors to officiate in any way at intermarriages. A complete prohibition against taking any action that would intimate that native Jewishness can be confirmed in any way but matrilineal descent.
