Stirling'S Commission & Letters Patent: Prerogative Autocracy On The Swan River Frontier

1. Executive Instruments Establishing the Swan River Colony

The administrative structure of the Swan River Colony was established through two interlocking executive prerogative instruments: Captain James Stirling's Royal Commission and the Royal Instructions issued by King George IV in December 1828 and formally executed in November 1830.^[1] Because the British Parliament's Swan River Act 1829 provided only temporary administrative authority, the Crown utilised Letters Patent to create the office of Governor and Commander-in-Chief, vesting Captain Stirling with virtually unlimited civil and military powers across unceded Bibbullmun country.^[2]

2. Unrestricted Land Granting Powers & Speculative Capitalism

The primary mandate codified within Stirling's Royal Instructions was the immediate surveying and granting of land to private British syndicates.^[3] Under a speculative scheme designed in London, settlers were promised 40 acres of land for every £3 of capital invested in goods, stock, and indentured servants.^[4] Stirling himself was granted a colossal personal estate of 100,000 acres, selecting prime riverfront land along Geographe Bay and Garden Island (Meeandip).^[5] The Letters Patent contained zero recognition of pre-existing Bibbullmun ownership, incentivizing settlers to aggressively seize fertile alluvial river flats, clear traditional hunting grounds, and foul sacred freshwater springs (gabba-koorliny).^[6]

3. Military Martial Power and the Pinjarra Massacre

Crucially, the Letters Patent combined civil gubernatorial governance with absolute military command.^[7] As Commander-in-Chief, Stirling had unrestricted authority to deploy the 63rd Regiment of Foot against the Aboriginal population.^[8] When Bibbullmun clans—led by resistance commanders Yagan and Calyute—defended their traditional territories against armed encroachment, Stirling declared martial law, executing summary hangings without trial.^[9] In October 1834, Stirling personally led a mounted military detachment that ambushed and massacred an estimated 30 to 80 Binjareb men, women, and children at the Battle of Pinjarra, demonstrating how executive prerogative was weaponized into state-sanctioned slaughter.^[10]

4. The Illegitimacy of Prerogative Title in Modern Jurisprudence

Modern constitutional law recognises that executive Letters Patent issued in London could not lawfully extinguish pre-existing First Nations imperium.^[11] Stirling's commission was a unilateral assertion of British domestic power that possessed zero validity against an independent, sovereign civilisation that had never submitted to Crown authority.^[12] Acknowledging the despotic violence authorised under Stirling's Letters Patent is vital for dismantling settler pioneer mythologies and establishing the historical imperative for sovereign bilateral treaties.^[13]
