Representatives of the NCAA's judicial arm appeared yesterday before a congressional subcommittee continuing its probe of the fairness of the NCAA system for investigating and disciplining alleged rule violations.

The Subcommittee of Oversight and Investigations conducted 10 days of hearings on the NCAA's enforcement program last year, culminating in 18 specific recommendations for reforming that program.

Most of the substantive recommendations were rejected last January by the Policy-making NCAA Council and the annual convention, and there was little to indicate yesterday that any of them would be adopted in full in the near future.

Although yesterday's hearing was the only one scheduled for this year, Subcommittee Chairman Bob Eckhardt (D-Tex.) told the representatives, "We will continue to watch with interest what your organization does. Your reforms which you say have been put in effect have not yet been tested. . . . We will watch you with concern."

Still in contention are NCAA policies on, for example, joint investigations by the NCAA and an accused college, evidentiary standards, access to transcripts of disciplinary hearings, the declaration of student ineligibility, right to counsel for minor violations and penalties, and a Mirandatype warning against self-incrimination.

Modifications have been made in some of these categories, Charles Alan Wright, a noted constitutional lawyer and chairman of the NCAA's hearing committee, said.

Other steps to aid accused colleges during investigations are planned, such as a manual explaining how to prepare a case for hearing, Wright said.

Also testifying for the NCAA were President William J. Flynn, Secretary-Treasurer James Frank and Bill Hunt, head of the enforcement program.
