26 U.S. Code § 6252 - Judicial review where administrative adjustment request is not allowed in full
No petition may be filed under this section after the Secretary mails to the partnership a notice of a partnership adjustment for the partnership taxable year to which the request under section 6251 relates.
If the Secretary mails to the partnership a notice of a partnership adjustment for the partnership taxable year to which the request under section 6251 relates after the filing of a petition under this subsection but before the hearing of such petition, such petition shall be treated as an action brought under section 6247 with respect to such notice, except that subsection (b) of section 6247 shall not apply.
A notice of a partnership adjustment for the partnership taxable year shall be taken into account under paragraphs (1) and (2) only if such notice is mailed before the expiration of the period prescribed by section 6248 for making adjustments to partnership items for such taxable year.
Except in the case described in paragraph (2) of subsection (c), a court with which a petition is filed in accordance with this section shall have jurisdiction to determine only those partnership items to which the part of the request under section 6251 not allowed by the Secretary relates and those items with respect to which the Secretary asserts adjustments as offsets to the adjustments requested by the partnership.
Any determination by a court under this section shall have the force and effect of a decision of the Tax Court or a final judgment or decree of the district court or the Claims Court, as the case may be, and shall be reviewable as such. The date of any such determination shall be treated as being the date of the court’s order entering the decision.
