Every civil court is backlogged with business misunderstandings / disagreements. People sue all the time for what may may not be legitimate reasons. All it takes is a simple majority of the jury for a victory. It's a highly subjective process whose most prized skill is the ability to sway a jury. More like coin toss, less like justice.

In business it's a bad idea to deceive business partners or to sign an agreement intending to ignore it. Your reputation will catch up with you, and don't be surprised when you get sued.
