I would hope the legal system is based on fixed pay with lawyers etc and what dominium and smartmatic are doing is based on the loss of projected profits.
Same with the Alex Jones case. If defamation effected the families due to loss of employment and relocation, but a billion dollars ....
The cynical side of me says it's so someone can buy another mansion.
To some extent you're comparing apples to oranges.
Damages typically come in two flavors: compensatory and punitive.
The plaintiffs in the Dominion and Smartmatic cases are corporations, whereas the plaintiffs in the Alex Jones cases were individuals. Damages are a fact question that is decided by the jury (unless its a bench trial). Individuals can be awarded compensatory damages for emotional pain and suffering, whereas businesses are generally limited to business losses. Of course, punitive damages above and beyond compensatory damages may also be awarded.
The amount of damages are almost always a major issue in civil lawsuits.
Putting a dollar amount on pain and suffering is highly subjective and it's extremely difficult to predict what a jury will do. Jones basically acted like a complete *asswipe (in my opinion) during the trials and he decided to go to the juries rather than settle. Reportedly, the highest amount awarded to any one plaintiff was $120 million. Someone could say that they think this is too high or too low, but the jury decides.
Business losses (damages) tend to be
somewhat more predictable than pain and suffering in the sense that there
tends to be more of an upper limit based on the size of the plaintiff's business. But, putting a dollar amount on damages to business reputation, etc. may still be difficult, and juries can go high. Fox apparently decided there was significant risk that the jury would award would be much more than the settlement amount. If Fox thought the case for damages was weak they could have gone to trial.
The damages listed in the original complaint may have little to do with the damages awarded by a jury or provided in a settlement. The facts have not been fully developed at this stage, but the plaintiff needs to list something. I believe one of the juries actually went above the amount one of the plaintiffs asked for in one of the Alex Jones lawsuits.
