Scarborough have been relegated from the Conference after an unspecified breach of rules and the league's board has now reinstated Altrincham.
After finishing bottom of the table, Scarborough earned a brief reprieve when Altrincham were docked 18 points for fielding an ineligible player.
The Football Association and Conference then asked Scarborough for financial, ownership and ground information.
Scarborough will start the Conference North season with a 10-point deduction.
Seadogs chairman Malcolm Reynolds congratulated Altrincham but said he had not been given any information about the rule his own club had breached.
Once we receive details of the alleged breach, we will consider our position then
"Altrincham had been treated very harshly for a technical offence and it's nice that they will retain their place for next season," he told Scarborough's website.
"However, as of 3 June we have not been charged with any breach and therefore have not had any opportunity to respond.
"We have been advised that the board will write to us with the details of its decision. We will also seek the minutes of the meeting.
"Once we receive details of the alleged breach we will respond. We will consider our position then.
"If we believe that the Conference has acted outside of its jurisdiction we reserve the right to seek immediate judicial redress through the courts."
However, a new rule stipulates that any club which a Conference decision has to pay the board's legal expenses, which could put such a move beyond Scarborough's reach.
