2700.6—Signing of documents.
When a person who appears in a representative capacity signs a document, that person's signature shall constitute his certificate:
(a)
That under the provisions of the law, including these rules and all federal conflict of interest statutes, he is authorized and qualified to represent the particular party in the matter; and
(b)
That he has read the document; that to the best of his knowledge, information, and belief formed after reasonable inquiry it is well grounded in fact and is warranted by existing law or a good faith argument for extension, modification, or reversal of existing law; and that it is not interposed for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation.
