There are a few types of federal jurisdiction.
The first is called federal question jurisdiction. If two people are suing each other under a federal law, as opposed to a state law, the lawsuit can be heard in a federal court.
Another type is diversity jurisdiction. If two people from different states are suing each other over a controversy with damages at more than $75,000, they can be heard in federal court.
For example; Alan is from Wisconsin, and he is suing Bob from Illinois for killing all of his cows and destroying his barn. His barn was worth $75,001. Alan would not want to be in an Illinois court because the Illinois court might like Bob more. Bob would not want to be in a Wisconsin court because they would like Alan more. So, this case would go to a federal court.
