Asking the Expert
My sister was ticketed for having farm animals on her property. Since the ticket is less than hiring a lawyer most people would just have to pay it and get on with their lives. But since her dad is a lawyer she could fight the ticket.
When the court date arrived the prosecuter thought he had a slam dunk case. He was shocked when he was asked what expert witness he had brought for the case.
Of course my sister is a large animal vet and counted as an expert in the field. My father read the local code, and found the exceptions that applied, and had his expert witness testify that the animals in question were defined as an exemption to what the code defined.
The case was dismissed by the judge after that. Story credit: Reddit / coh_phd_who
