The case will likely be decided by a panel of three of the sixteen members. Three of the 16 are women, from England, Mexico and Thailand.
Rubiales is a UEFA vice president and was the European soccer body’s most senior delegate at the biggest game in women’s soccer.
The Spanish soccer federation, which the 46-year-old Rubiales has managed for five years, is expected to convene an emergency meeting Friday in Madrid where the agenda includes questions on the subject.
It's not clear whether the meeting is an attempt to rally support for Rubiales or a reaction to the overwhelming calls for his resignation from the Spanish government and soccer officials.
Rubiales is presently leading Europe's bid to host the men's World Cup in 2030. He previously ran the Spanish players' union for eight years before becoming federation president in 2018.
Along with Portugal and Morocco, Spain is also considering an offer from Ukraine.
