The jury is the ultimate trier of fact. In our democratic society, we place high value on the idea of being judged by a panel of your peers. In addition, it allows the accused to be judged by the prevailing community standards. The jury is supposed to be more in touch with the average person than the average judge would be. Generally, since the jury is held is such high regard, the court of appeals is hesitant to overturn any of their decisions. The court explained this notion in a case arising from Cameron Parish, Louisiana.
In that case, a truck driver swerved to avoid a sign placed there by the Department of Transportation and Development. The sign was too far on to the road, the truck driver did not notice the misplacement fast enough, and had to swerve to avoid hitting the sign. When he swerved, he lost control and ended up in a ditch that Hurricane Ike damaged. The truck flipped and, although the truck driver was not harmed upon the collision, he was stuck in the vehicle upside-down. After forty-five minutes of being pinned upside-down, the truck driver died of asphyxiation. His wife and three children sued the DOTD based on general damages, lost past and future wages, survival damages, and funeral expenses.
The lower court found that the DOTD was fifty percent at fault and the truck driver was also fifty percent at fault. As such, the lower court awarded damages that amounted to $700,000 in total. Fault determinations are extremely fact intensive, so the lower court, as the trier of fact has broad abilities to make these determinations. As such, they are difficult to overturn in the court of appeals.
