I’m not sure about the Seattle or court part.
I appeared in the New York Times 5/5/75. In an Article entitled “Responsa: The Law as Seen By Rabbis for 1,000 Years”
The relevant quote attributed to R” Moshe is:
“You can’t wake up in the morning and decide you’re an expert on answers. If people see that one answer is good, and another answer is good, gradually you will be accepted.”
(Though he didnt speak English so its obviously not verbatim)
The entire article is interesting. With Google’s help it is easy to find
