Subject: File No. SR-NASD-2003-158

Dear Sir:

On May 4, 2006 the NASD indicated on its website that it had filed Amendment No. 5 to the rewrite to the NASD Code of Arbitration Procedure. (See Filing 2003-158.)
This filing includes substantial changes from the last amendment to the

Rewrite, which will materially affect investors.

A large part of my law practice involves representing public customers in NASD arbitration proceedings. I also represent broker dealers and registered representatives from time to time.

The rewrite is of great concern to me and my practice. Based on the many comment letters already received on the rewrite, it also an issue of great concern to the public. Yet I understand that the NASD proposes this rewrite without public comment. Based on the importance of the rewrite and great public concern, I request that the SEC commence a new comment period to allow public input on this important new filing.

Thank you for your consideration

Very truly yours,

Thomas D. Mauriello
