On 16 July 2020, the Government of Portugal decided to start the process whereby Portugal will, in due course, become a party to the United Nations Convention on Contracts for the International Sale of Goods (CISG).
Today, the Convention is internationally in force for 91 States. Once in force for Portugal, it will be binding on all the current members of the European Union, with the exception of Ireland and Malta.
UPDATE (7 August 2020) — On 7 August 2020, the decree approving the accession was published on the Diário da República, the official journal of Portugal, together with the Portuguese official translation of the Convention. Many thanks to Dário Moura Vicente for drawing the attention of the blog editors on this development.
