(a) the
Treasurer is of the opinion that a person liable to pay royalty—
(i)
has not made a payment of royalty when it falls due; or
(ii)
has not paid royalty in accordance with the
royalty assessment principles (and any related provision under this Act); or
(iii)
has not paid royalty in accordance with any agreement or
determination that applies under section 17 or 17A; or
(iv)
has not paid royalty in accordance with any other
relevant requirement; or
(b) the
market value of minerals has been determined, for the purposes of assessing
royalty, according to a tenement holder's estimate of the reasonable value of
the minerals under section 17(6)(b)(vi) and the Treasurer does not agree
with the estimate; or
(c) a
person makes a default in furnishing a return; or
(d) the
Treasurer is not satisfied with a return furnished by a person; or
(e) the
Treasurer has reason to believe—
(i)
that royalty is payable by a person who has not furnished
a return; or
(ii)
that a person who has furnished a return has made an
overpayment of royalty,
the Treasurer may, after consultation with the Minister, make an assessment of
royalty the person is liable to pay.
(2) Without limiting
subsection (1), the Treasurer may, after consultation with the Minister,
on application or on the Treasurer's own initiative, review and revise an
earlier assessment of royalty (and the revision will then be taken to be a new
assessment for the purposes of this Act).
(3) For the purposes
of making an assessment under subsection (1) or (2), the Treasurer may
estimate the amount of royalty payable by a person and may base the estimate
on any matter the Treasurer considers relevant.
(4) The Treasurer must
cause a copy of an assessment under this section to be served on the person
liable to pay the royalty or to whom a refund is payable.
(5) If, as a result of
the Treasurer's assessment, a lower amount of royalty is payable for the
relevant return period or periods, the Treasurer must—
(a)
refund the amount of the excess to the person; or
(b) set
off the amount against a future liability to make payments of royalty under
this Act.
(6) A person on whom a
copy of an assessment is served may, within 1 month after the date of
service, appeal against the assessment to the ERD Court.
(7) On the hearing of
an appeal, the ERD Court may, if satisfied on the basis of evidence provided
by the appellant that the assessment of the Treasurer is incorrect, vary the
assessment of the Treasurer to such extent as it thinks fit.
