The Treaty of Cession, 6 August 1861

Article I
Paragraph 4 states "I, Docemo, do, with the consent and advice of my Council, give, transfer, and by these presents grant and confirm unto the Queen of Great Britain, her heirs, and successors forever, the port and Island of Lagos with all the rights, profits, territories, and appurtenances whatsoever thereunto belonging, and as well the profits and revenue as the direct, full, and absolute dominion and sovereignty of the said port, island, and premises, with all royalties thereof, freely, fully and entirely and absolutely. I do also covenant and grant that the quiet and peaceable possession thereof shall with all possible speed, be freely and effectually delivered to the Queen of Great Britain, or such person as Her Majesty shall thereunto appoint for her use in the performance of this grant; the inhabitants of said island and territories, as the Queen’s subjects, and under her sovereignty, Crown, jurisdiction, and government, being still suffered to live there.

Every treaty expires after 100 years.
Now 160 years.
Not a news that King Docemu ceded Lagos to British in 1860 under deception and duress.
UK amalgamated Nigeria in 1914 which also expired in 2014.
The validity of Certificate of Occupancy also expires after 99 years.

All those are now null and void.
