A famous family law / defense attorney decided to fight for a catalytic converter recycling company. These types of companies buy catalytic converters from the public and remove the valuable minerals and resell them to be used again for other applications. The issue at hand was the company was tricked into buying empty converters.
This is quite common in the business and can be hard to avoid especially if you are buying thousands of units at once. The buyer cannot tell how full each converter is until they are opened up. There are ways the materials inside the converter are removed and the converters are sealed back up again to be sold.
Fraud attorneys will regularly fight these types of cases because many times the fault lies far beyond the seller of the converters. Since these are sold in such large lots many times the seller is actually a reseller and had no knowledge of the exactly quality of the lots being sold and was just trusting the word of the initial buyer. This can get quite confusing and is best for the courts to settle. These cases are usually handled by state courts.
One way or another this will be made right it will depend on many factors and state courts usually taking several years and many times more money will be spent on court costs than actually on the converters. So the buyer has to be careful not to take this to far or it will be for not.
