Final answer:
To avoid dismissal of his suit, John Verble has a legal obligation to support his claims with more facts. He also owes an ethical duty to back up his claims with more facts using the IDDR approach.
Step-by-step explanation:
To avoid dismissal of his suit, John Verble does have a legal obligation to support his claims with more facts. In the legal system, a complaint must contain enough factual information to state a claim that is plausible on its face. Without additional facts, Verble's complaint may be considered too vague or speculative, and thus subject to dismissal.
Additionally, Verble owes an ethical duty to back up his claims with more facts. The IDDR approach (Inquiry, Debate, Decision, and Responsibility) emphasizes the importance of providing reliable evidence to support one's claims. As an ethical principle, it is expected that Verble would gather and present sufficient evidence to support his allegations of illegal activity and retaliation.
