Of course it did. The people who resided in Mississippi could no longer sue in the United States District Court in Mississippi. The people who resided in Mississippi could no longer exercise, assert or enforce their constitutional rights as guaranteed by the United States Constitution in Mississippi. The people who resided in Mississippi could no longer participate in elections for the selection of United States House of Representatives from Mississippi or for the selection of President of the United States. United States officers who lived in Mississippi could no longer enforce the laws of the United States in Mississippi.
I'm not sure that you understand what the secessionists meant by "secession." The "secessionists" believed that post "secession," United States citizens living in Mississippi could no longer depend upon the enforcement of United States laws or the provision of United States services in Mississippi. The whole purpose of "secession" was to terminate the governance of the United States government in the geographical areas that were "seceding." And, that necessarily meant that persons residing in those areas could no longer depend upon United States laws or services unless the United States government sent troops to those areas. And, of course, that's what the United States government did.
It may sound crazy to you now, but the "secessionists" actually intended to replace the government of the United States with a new, more local government that they called the "Confederate States of America." And, they never even asked the United States government for permission.
On the 4th of February, the Confederate Congress, composed of delegates from the States of Alabama, Florida, Georgia, Louisiana, Mississippi, and South Carolina, met at Montgomery, Alabama.
The men duly authorized to represent Mississippi were:
MISSISSIPPI-—Riley P. Harris, W. S. Wilson, A. M. Clayton, Walker Brooke, W. S. Barry,.T. T. Harrison, J. A. P. Campbell.
After some discussion the convention adopted provisionally the Constitution of the United States, with some important changes,
The preamble read as follows:
“We, the deputies of the sovereign and independent States of South Carolina, Georgia, Florida, Alabama, Mississippi, and Louisiana, invoking the favor of Almighty God, do hereby, in behalf of these States, ordain and establish this constitution of the provisional government of the same, to continue one year from the inauguration of the President, or until a permanent constitution or confederation between the said States shall be put in operation, whichsoever shall first occur.”
The provisional constitution possessed notable articles.
Sixth article, of the second clause, said:
“The government hereby instituted shall take immediate steps for the settlement of
all matters between the States forming it, and their late confederates of the United
States, in relation to the public property and public debt at the time of their withdrawal
from them; these States hereby declaring it to be their wish and earnest desire to adjust every thing pertaining to the common property, common liabilities, and common
obligations of that union, upon principles of right, justice, equity, and good faith.”
