I see. So what you are saying then is that any ligation he created during his time as provisional leader of the Confederacy which began in February 1861 when he was inaugurated to said position until he assumed the office of full Presidency in February of 1862 did not have any legal authority since as you say he had no treaty-making power.
This invalidates any legitimacy to the commission he sent to negotiate with the North in February of 1861, the original source in which you mistakenly made the claim that Lincoln met Davis, which you would have to agree now seems pretty far afield.
So the question now should be, if he had no legal authority to broker a deal with the North when he was the provisional President of the Confederacy, why did he even send a ligation to attempt it, and what reason would any sovereign government have to give this illegitimate commission the time of day.
“This invalidates any legitimacy to the commission he sent to negotiate with the North in February of 1861”
The commission was sent in February of ‘62.
