Final answer:
The incorrect statement about limitations of mediation is that it is usually more expensive than adjudication or arbitration. In fact, mediation is typically less expensive and chosen for its cost-effectiveness.
Step-by-step explanation:
Mediation is often chosen because it is typically less expensive than either adjudication or arbitration. Contrary to the claim in option D, mediation is not usually more expensive than these alternative dispute resolution methods, as it tends to involve fewer legal costs and can be concluded more quickly. However, its success does depend on the willingness of all parties to participate and seek a mutual agreement. Therefore:
- Not all conflict parties will agree to work with the 'enemy' (A).
- Mediation may not be worthwhile for minor conflicts (B).
- It may not be suitable for certain types of relationships (C).
- Mediation is usually less expensive than adjudication or arbitration (D).
Thus, mediation being more expensive is the incorrect statement and the answer to the question.
