[Avodah] Ran's theory of secondary justice system to handle cases not covered by halacha

[M Cohen]

I just came across a rabainu Yonah (Shaarai teshuvah, shaar 3, seif 221)
that says
a similar idea.

he says that although in general a single witness should not testify 
(because a single witness's testimony is useless)
that in the case of avairos ben Adam l'chavairo (ie theft, damage, pain,
etc)
a single witness SHOULD tell the appropriate authorities so that justice
will be done
