        3.  An executed copy of the Indenture dated March 3, 1999 (the "Senior
            Subordinated Notes Indenture"), by and between the Authority and
            State Street Bank and Trust Company, including the form of Exchange
            Note to be issued pursuant thereto, as filed as Exhibit 4.7 to the
            Registration Statement.

        4.  The Constitution of the Mohegan Tribe, as certified by the Recording
            Secretary of the Management Board of the Authority on the date
            hereof as being complete, accurate and in effect.

        5.  The Mohegan Tribal Ordinance No. 95-2 "And Ordinance Establishing
            the Mohegan Tribal Gaming Authority" dated July 15, 1995.

        6.  Resolutions of the Management Board of the Authority adopted on
            February 18, 1999 as certified by the Recording Secretary of the
            Management Board of the Authority on the date hereof as being
            complete, accurate and in effect, relating to the issuance and sale
            of the Exchange Notes and arrangements in connection therewith.

        In our examination of the aforesaid documents, we have assumed the
genuineness of all signatures, the legal capacity of all natural persons, the
authenticity, accuracy and completeness of all documents submitted to us, and
the conformity with the original documents of all documents submitted to us as
certified, telecopied, photostatic or reproduced copies. This opinion letter is
given, and all statements herein are made, in the context of the foregoing.

        This opinion letter is based as to matters of law solely on applicable
provisions of the contract law of the State of New York (but not including any
statutes, ordinances, administrative decisions, rules or regulations of any
political subdivision of the State of New York). We express no opinion herein as
to any other laws, statutes, ordinances, rules or regulations.

        Based upon, subject to and limited by the foregoing, we are of the
opinion that the Exchange Notes have been duly authorized on behalf of the
Authority and that, (i) following the effectiveness of the Registration
Statement and receipt by the Authority of the Senior Notes in exchange for the
Senior Exchange

Notes and receipt by the Authority of the Senior Subordinated Notes in exchange
for the Senior Subordinated Exchange Notes as specified in the resolutions of
the Management Board referred to above, and (ii) assuming due execution,
authentication, issuance and delivery of the Senior Exchange Notes and Senior
Subordinated Exchange Notes as provided in the Senior Notes Indenture and Senior
Subordinated Notes Indenture (together, the "Indentures"), respectively, both
sets of Exchange Notes will constitute valid and binding obligations of the
Authority entitled to the benefits of the Indentures and enforceable in
accordance with their terms, except as the enforcement thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights (including, without limitation, the effect of statutory and
other laws regarding fraudulent conveyances, fraudulent transfers and
preferential transfers) and as may be limited by the exercise of judicial
discretion and the application of principles of equity including without
limitation, requirements of good faith, fair dealing, conscionability and
materiality (regardless of whether the Exchange Notes are considered in a
proceeding in equity or at law).

        The Opinion expressed in the Paragraph above shall be understood to mean
        ========================================================================
only that (i) if there is a default in performance of an obligation, (ii) if a 
==============================================================================
failure to pay or other damage can be shown and (iii) if the defaulting party
=============================================================================
can be brought into a court which will hear the case and apply the governing
============================================================================
law, then, subject to the availability of defenses, and to the exceptions set
=============================================================================
forth in the Paragraph above, the court will provide a money damage (or perhaps 
===============================================================================
injunctive or specific performance) remedy.
===========================================

        We assume no obligation to advise you of any changes in the foregoing
subsequent to the delivery of this opinion letter.  This opinion letter has been
prepared solely for your use in connection with the filing of the Registration
Statement on the date of this opinion letter and should not be quoted in whole
or in part or otherwise referred to, nor filed with or furnished to any
governmental agency or other person or entity, without the prior written consent
of this firm.

          We hereby consent to the filing of this opinion letter as Exhibit 5.1

caption "Legal Matters" in the prospectus constituting a part of the
