Firm annotation
The elements are those of Section 297 grievous bodily harm plus any one of the Section 289 aggravating circumstances, for example premeditation, cruelty, harm to an ascendant or an official on duty, or acting to facilitate another offence. The aggravating circumstance does not change the ten-year maximum but raises the minimum term from six months to two years, so it materially increases the floor of the sentence. It is the aggravated top tier of the bodily-harm ladder, standing to Section 297 as Section 296 stands to Section 295.
Why this matters in practice
Exposure carries a two-year minimum, so unlike the lighter assault tiers there is little room for a purely nominal sentence once conviction stands. The central defence lines are to contest the grievous nature of the injury, which can drop the case to Section 297 or 295, and to contest the Section 289 aggravating circumstance, which can drop it to Section 297. Both turn on close reading of the medical and factual record, and given the heavy exposure early specialist advice is important.

Supreme Court Judgment No. 218/2560 (2017)
Section 298 covers grievous bodily harm committed with a Section 289 aggravating circumstance such as premeditation; the aggravated grievous-harm conviction stands or falls on whether that circumstance is proven.
The first-instance court convicted the defendant under Sections 297(8) and 298 with Section 86 as a supporter and imposed four years imprisonment, but the appellate court set aside the premeditated grievous-harm conviction and the accompanying compensation claim.

Supreme Court Judgment No. 7590/2560 (2017)
Theft under Section 335 (1)(7)(8) paragraph two (former) carries one to seven years, so it is not a case with a minimum of five years' imprisonment within section 176 paragraph one of the Criminal Procedure Code. The prosecution therefore need not call evidence to support a plea of guilty, and the court may convict on the plea alone.
The Court of Appeal Region 2 had convicted the defendant of aggravated grievous bodily harm under Section 298 with Section 83, imposing six years reduced by half to three, and had dismissed the joint theft charge. The Supreme Court held that dismissal wrong: the theft charge did not require evidence in support of the plea, so the trial court could convict on it. It also held that Amendment Act No. 26 B.E. 2560, which raised the fine under Section 335 paragraph two, was not more favourable to the defendant, so the law in force when the offence was committed applied. It added one year for the theft after reduction, making four years in all.
