How do I repeal rabbinic laws? Who to contact? What is the process? Please give me specific names and direct contact information. I need real decision makers who can really change the laws. Online or phone # would be great. PM me if it is private. I would rather contact them than write my questions here on this forum. This would really help me out. Thanks.
As far as I know there are currently no rabbis who are actively involved in legislating rabbinc-level laws. Those laws were set in stone centuries ago. As DoubleAA mentioned in the comments on your question, rabbinic laws could theoretically be repealed by a court under certain circumstances; however, there is not currently a court as great as the Sanhedrin in order to do this.
As far as modern decision-making goes, current rabbis are not determining new laws. Modern rabbis simply interpret the laws that have been in place for a long time in a modern context. There are a few great rabbis who answer the most difficult questions; however, most scenarios that you will encounter in a day-to-day context are unlikely to be so complex that such a great rabbi must be contacted. Usually your local Orthodox rabbi will be sufficient to tell you what you should do in a given circumstance. He will not be creating the law; he will just be telling you the law that is already on the books, and he doesn't have the power to change it.
Orthodox Jews live their lives based on rules explained/instituted by great Rabbis many years ago.
Throughout the generations many learned people have continued to interpret and apply those laws. While in theory anyone could say anything they want today, people would only listen if you are learned, serious and respect precedent.
While nowadays there is no central leader that everyone accepts, there is often consensus on the much earlier Rabbi’s decisions.
It is practically impossible to overturn actual rabbinic laws today until the Jewish people get it together enough to institute a court greater than the one at the time when the oral law was finalized in written form.
Without one communal leader, each community has a Rabbi or Rabbis that help lead their community and make small decisions about applying laws to their community. That is probably who you would want to find and talk to, and if necessary they can point you to an appropriate Rabbi who is an expert in more specific fields.
