Firm annotation
Section 110 protects three high offices, not one: it covers violence against the person or the liberty of the Queen or the Heir-apparent, and violence against the body or the liberty of the Regent. The penalty is imprisonment for life, or a fixed term of sixteen to twenty years, which is one step below the offences against the King in Sections 107 and 108 because the base offence here carries no death penalty. An attempt is punished the same way, provided for in the section itself rather than by the general rule in Section 80. Killing any of these three is the graver offence in Section 109. As with the rest of this group, the offence is committed by a physical act rather than by any expression, which is what separates it from Section 112, and Section 111 makes a supporter in any offence under Sections 107 to 110 liable to the same punishment as a principal.
Why this matters in practice
Section 110 protects three people, not one: it covers violence against the person or the liberty of the Queen or the Heir-apparent, and violence against the body or the liberty of the Regent. The punishment is severe but, unlike Sections 107 to 109, does not include death for the base offence: life imprisonment, or a fixed term of sixteen to twenty years. An attempt carries the same punishment, provided for in the section itself rather than by the general rule in Section 80. Section 111 is a separate provision and makes a supporter liable to the same punishment as a principal, so the two-thirds reduction for supporters in Section 86 does not apply. The offence requires a physical act rather than any expression, which distinguishes it from the speech offence in Section 112, and killing any of these three is Section 109. Given the length of the sentences at stake, specialist criminal defence should be engaged immediately.
