What is Per Diem Argument?

A method of calculating pain and suffering damages by assigning a specific dollar amount to each day the plaintiff has suffered and will continue to suffer from their injuries.

Understanding Per Diem Argument

The per diem argument is a persuasive trial technique used during closing arguments. The attorney might suggest a daily rate, such as $100 or $200 per day, and multiply it by the number of days the plaintiff will experience pain. For example, $150 per day for 10 years equals $547,500 in pain and suffering damages. Some jurisdictions do not allow per diem arguments, so attorneys must check local rules.
