Had it been exacted ... that each Baronet, with a stated number of colonists, should take personal possession, it is certain the number of applicants would have been scanty indeed. To obviate this difficulty it was held, by a fiction of the law, that the usual legal form of taking possession by an instrument of seisin, or infeftment of lands on the other side of the Atlantic, should take place within the Castle of Edinburgh.
The lands included in the baronies of New Scotland were resigned by Sir William Alexander into the hands of the king [Charles I], who re-granted them to the knights baronets. Thus the lands and titles were obtained directly from the sovereign. Infeftment, it was ruled, should be "expede" at the Castle of Edinburgh.
As such like parties were not baronets of the colonising kind, and yet were desirous, no doubt, to take seisin of their purchased grants in Nova Scotia, old Sir William, always provident, had his remedy prepared. He had had it laid down in the formula of the charter, that "the realm of Nova Scotia, and original infeftment thereof, is holden of the kingdom of Scotland, and forms part of the County of Edinburgh." Argal, to take seisin and instruments of possession "on the Castle Hill of Edinburgh," formed a cure for every difficulty, and served the desired purpose as well as if the baronets had indulged in a trip to the actual site of their new possessions.
The precept for the charter for each Baronet was granted in the name of Sir William Alexander, who surrendered to the Crown the respective portions of his Lordship of Nova Scotia to be attached to the Baronetcy with all rights of regality. The Baronets were allowed to take possession of their territory by deed of infeftment within the walls of Edinburgh Castle.
The colony was named New Scotland, and by a legal fiction, it was, for administrative purposes, connected with Edinburgh. In order to raise men to help found the colony, the King instituted the Order of Baronets of Nova Scotia. This hereditary title was given to gentlemen who arranged to send a certain number of men and to pay a certain amount of money to help to found the Plantation of New Scotland, .... The Order was instituted in 1625, the ceremony being held in the courtyard of Edinburgh Castle. By Royal Decree that place was declared to be an integral part of the new colony. This decree has never been annulled.
In fact, some of the boat docks for Canadian cabins sit on the U.S. side of the border.
Under Scots Law, Baronets "take sasine" by receiving symbolic "earth and stone" on the actual land. Part of Edinburgh Castle was deemed granted to Sir William as part of Nova Scotia. The Baronets were installed with "earth and stone" there while standing in Nova Scotia.
Baronets could receive their patents in Edinburgh rather than London, and an area of Edinburgh Castle was declared Nova Scotian territory for this purpose.
For the purpose of taking possession of his lands after the feudal fashion then prevailing, Nova Scotia was made a part of the county of Edinburgh, and at Edinburgh Castle the ceremony of Sasine was performed. ... [excerpt of 1621 charter:] And we will, and grant, and, for ourselves and our successors, do decree and ordain, that one seisin, at this time, by the said Sir William, and his aforesaid, upon any part of the soil of the said lands and province above written, shall, in all time to come, stand, and be a sufficient seisin for the whole region, ...
Before this charter was ratified by the Scots Parliament, his Majesty [James VI] died; when, in 1625, the grant was renewed by his successor [Charles I] in form of a Charter of Novodamus, proceeding upon the above narrative, and conceding, over and above, additional powers to Sir William Alexander. These charters are in the usual form of feudal conveyances employed by the law of Scotland, but erecting Nova Scotia into a Barony, and declaring sasine at the castle of Edinburgh to be equivalent to sasine on the lands themselves.
The Tribunal determines that, in these circumstances, area 7.1 forms part of the territory of Slovenia, and the boundary runs along Slovenia's cadastral limits. The Tribunal recognises that the delimitation thus made on the basis of the cadastral limits is one of great complexity. The cadastral boundary creates numerous meanders and even enclaves.
In 1996, the inhabitants of Saint-Pierre-et-Miquelon had further reason to protest following the Canadian decision to take Sable Island (175 km off the coast of Nova Scotia) into account as the basis for the extension of its EEZ to 200 miles towards the open sea. The knock-on effect of this unilateral decision was that the French zone was hemmed in by the Canadian one.
