John Jones is a paralegal working at the XYZ law firm. The firm is handling a large class action involving potentially thousands of plaintiffs. John has been instructed to screen the potential plaintiffs in the class. John tells those he screens out (using criteria provided by the firm) in writing or verbally that "Unfortunately, our firm will not be able to represent you."

a) Any ethical problems here?

The only thing I can think of is that paralegal cannot make that determination because he was asked to screen not to make a final decision, but what model rule is applied to that if there is a model rule that describes this type of ethical problem.

b) What else can be wrong there?
