Ridicuous enforcement of condo association rules challenged?

The homeowners association of a condominium I own for investment has a rule prohibiting using the enclosed patio of a ground unit from being used for "storage, free of liter and debris." I have been cited because my tenant's children left some toys on the patio, items which could only have been viewed if someone made an effort to peer over the wall surrounding it. I am incensed with this obtrusiveness. Is there any precedent for challenging the reasonableness of HOA rules? Thanks!
