HOA parking assignment

Question -- the condo association where we live has assigned parking spaces,
one per unit, which have been the same since the units were built 30 years
ago.  The assigned locations have been based on proximity to units.
Recently, a new board member was elected who decided to change our assigned
spot into visitor parking, and assign our spot further away where visitor
parking used to be, without contacting us.  We only noticed once the spots
were repainted.  This board member lives across the street with an existing
adjacent parking spot, where this new visitor spot is the next closest to
her unit.  I approached this board member about this and she stated that she
has "an old grandpa that visits" and that she needs the visitor spots more
than others.  The HOA regulations probably state something like the board
has full authority to assign parking spaces, etc.  Is there any legal
recourse in this situation?
