The dispute appeared to have been forgotten until the 1930s when the government of General Jorge Ubico claimed that the treaty was invalid because the road had not been constructed. Britain argued that because neither the short-lived Central American Federation (1821–1839) nor Guatemala had ever exercised any authority in the area or even protested the British presence in the 19th century, British Honduras was clearly under British sovereignty. In its constitution of 1945, however, Guatemala stated that British Honduras was the twenty-third department of Guatemala.
