I have been involved in the legal system a few times for the company i work for ( dozens of times)
I have been involved as an expert witness several times.
I sat through maybe 15 hours total of testimony on one case. Electrician, general contractor, witnesses.
Do you know what decided the case after 100's of pictures and evidence, statements? The contractor forgot to put a completion date on the contract.
Unfinished, unprofessional work, contracts for the same room with different prices on different dates, statements from electrician and General contractor stating the work was poorly done and or never done at all.
Failure to put a completion date is consumer fraud and legal fees can be recovered. Nobody cared the guy lied and cheated.
