Material facts

Following an audit for 2012–2018, GRA assessed Seadrill at about US$305.6 million. Seadrill paid an agreed US$12.5 million deposit and lodged an objection.
GRA reduced the liability, including through a 1 December 2020 objection decision. Seadrill wrote again on 30 December 2020 and relied on an 8 October 2021 payment letter as a fresh objection decision.
Seadrill filed its High Court appeal in November 2021; GRA maintained that time had already expired.

Questions before the court

Whether the 1 December 2020 objection decision was itself a tax decision capable of further objection.
Whether the 30 December 2020 letter was a valid objection and the 8 October 2021 letter a new objection decision that restarted time.

What the court held

The 1 December 2020 letter was an objection decision under section 43 and section 41(1)(d) excluded it from tax decisions open to another objection.
The 30 December letter was not a valid statutory objection; without a valid antecedent objection, the 8 October 2021 communication could not be a section 43 objection decision.
The later correspondence did not restart the appeal period and the High Court appeal was incompetent.

Ratio decidendi

Act 915 creates a sequence: a tax decision may be objected to under section 42, the Commissioner-General determines it under section 43, and the objection decision may be appealed under section 44. Serial objections do not replace that appeal, and a later communication cannot trigger a new appeal period unless it is the product of a valid statutory objection.

Obiter

Taxing powers, objection rights and appeal rights must be found and confined by the governing statute.

Appeal dismissed in its entirety; Court of Appeal judgment of 16 November 2023 and High Court ruling of 5 April 2022 affirmed.
