It has been asserted that "Between the re-establishment of British rule on the Falkland Islands in 1833 and the ratification of the treaty, Argentina sent annual protests to the British government by means of the Message to Congress, thereby maintaining Argentina's claim to the islands". Following the treaty, such protests ceased and Argentina did not protest again diplomatically until 1888. The matter was not raised again before the Argentine Congress until 1941. The British government cites this change as evidence that "there is no question over the sovereignty of the Falkland Islands".
