The Somali Act of Union was retroactively legalized after a seven-month legal gap
Evidence
Although the unification of the two Somalilands was put into practice on July 1, the Act of Union’s legal status briefly remained unresolved. … However, the legal formalities had not been completed in time … [and] the matter was clarified seven months later by the adoption of the new Act of Union with retroactive effect as from July 1, 1960 for the whole of the Republic. — Abdi Ismail Samatar, Africa’s First Democrats, 527
