Which of the following is an improper purpose under Rule 11(b)(1)?

• A. To harass
• B. To cause unnecessary delay
• C. To needlessly increase the cost of litigation
• D. All of the above

Answer: (D)

Rule 11(b)(1) bars presenting a pleading for an improper purpose. The examples it lists—harassment of the other party, causing unnecessary delay, and needlessly increasing the cost of litigation—are all designed to prevent filings used to weaponize litigation rather than to advance legitimate claims or defenses. Each motive described undermines the integrity of the judicial process, so when a filing is motivated by any of these aims, it falls outside the certification required by Rule 11. Since all three motives fit the improper-purpose standard, the correct choice is that all of the above are improper.
