There are different types of jurisdiction. Subject-matter, personal, venue, procedural, etc.

In this case, reading the opinion w/dismissal, there were two factors involved:

1) The court determined her individual claim was moot because the FBI had already discontinued the forfeiture proceedings & returned her seized property, with interest, before the appeal

2) Her class claim was also dismissed because no class had been certified before her individual claim became moot
