The Central Electoral Board (JEC) has ruled that postal votes destined for Melilla that are deposited in mailboxes instead of being sent by certified mail will not be valid. The votes that are legally considered invalid, are not sent to the polling stations but to the Electoral Board of Zone for recount.

A judicial investigation is open in the Court of First Instance and Instruction No. 2 of Melilla in relation to an alleged plot about postal voting, which has led to the arrest of several people.
