What jurisdictional issue exists regarding the contract between the limited liability company and the corporation?

The presence of a lack of subject-matter jurisdiction due to non-diversity highlights an essential principle in federal jurisdiction, specifically regarding cases that involve parties from different states. In cases where a limited liability company (LLC) and a corporation are involved, the jurisdictional issue may arise if the parties are not completely diverse. Federal courts require complete diversity between all plaintiffs and all defendants to establish jurisdiction based on diversity of citizenship.

If both the LLC and the corporation are determined to be citizens of the same state, then the federal court would lack subject-matter jurisdiction based on diversity, necessitating that the case be brought in a state court instead. This concern is particularly relevant when assessing the litigation landscape and ensures that parties have recourse in an appropriate court that can handle their dispute effectively.

By contrast, the other issues presented do not directly pertain to jurisdiction as it is defined within the federal framework or in relation to the parties' citizenship. For instance, improper venue pertains more to the geographic appropriateness of the location where a case is filed rather than whether a court has authority over the subject matter. Insufficient evidence relates to the merits of the case rather than jurisdictional validity, and an unenforceable contract would suggest issues with contract formation or legality
