It shall be unlawful, except in accordance with proper judicial order
or as otherwise provided to the fullest extent permitted by law, for
the Receiver of Taxes or employee or designee of the Receiver of Taxes
to divulge or make known in any manner the rents or other information
relating to the business of a taxpayer contained in any return required
under this article. The officers charged with the custody of such
returns shall not be required to produce any of them or evidence of
anything contained in them in any action or proceeding in any court,
except on behalf of the Receiver of Taxes in an action or proceeding
under the provisions of this article or on behalf of any party to
any action or proceeding under the provisions of this article when
the returns or facts shown thereby are directly involved in such action
or proceeding, in either of which events the court may require the
production of, and may admit in evidence, so much of said returns
or of the facts shown thereby as are pertinent to the action or proceeding
and no more. Nothing herein shall be construed to prohibit the delivery
to a taxpayer or his/her duly authorized representative of a certified
copy of any return filed in connection with his/her tax nor to prohibit
the publication of statistics so classified to prevent the identification
of particular returns and items thereof or the inspection by the Town
Attorney or other legal representatives of the Town or by the District
Attorney of any county of the return of any taxpayer who shall bring
action to set aside or review the tax based thereon, or against whom
an action or proceeding has been instituted for the collection of
a tax or penalty. Returns shall be preserved for three years and thereafter
until the Receiver of Taxes permits them to be destroyed.
