In Italy, you can be a part-time Judge and a practicing attorney. So there were these identical twins, one of whom was a part-time Judge and a lawyer. The other sister had finished law school, but was not a practicing attorney, or so everyone thought.
Seems the Judge (Gabriela Odisio) was double-booked, and asked her sister to stand in for her! And it worked the other way too, with Patrizia sitting as a Judge for her sister. It worked for 3 years! How did they get busted? Slip of the lip. A client overheard them talking about it!
