Example wrong choices
20627_ruth_hymn_poster_contract · CIVIL_PROCEDURE · Choice ANo, because state-law contract claims can never be heard under diversity.
Why it's attractive
The student sees a state-law contract claim and overcorrects into thinking federal court is unavailable. The breaker is the categorical word never; diversity jurisdiction can hear qualifying state-law civil actions.
Why it's wrong
The word never makes an overbroad category claim. State-law contract claims are not categorically excluded from diversity jurisdiction.
Spot it next time
Ask whether the answer is making a categorical claim broader than diversity doctrine allows.
20627_ruth_hymn_poster_contract · CIVIL_PROCEDURE · Choice BYes, because any change in citizenship before trial controls.
Why it's attractive
The student grabs the later Colorado move and treats any pretrial citizenship change as controlling. The breaker is the filing-day Gold Key; later citizenship changes do not create diversity missing at filing.
Why it's wrong
The word any and the before-trial timing both fight the filing-day snapshot.
Spot it next time
Circle the complaint-filing date and check citizenship there first.
20627_ruth_hymn_poster_contract · CIVIL_PROCEDURE · Choice DYes, because diversity is measured when Daniel first answers.
Why it's attractive
The student treats the answer deadline as the moment when jurisdiction becomes fixed. The breaker is that the timing runs the other way: citizenship is measured when the complaint is filed.
Why it's wrong
The response-date timing reverses the filing-day rule.
Spot it next time
Say: filing first, response later; jurisdiction is tested at filing.
