Hi
A strange thing to 'push' but the definition of residential and holiday homes will be defined in the escrituras of your properties, if they are residential homes they will be classified as Urbanistica, if they are Holiday homes then they are Touristica. Essentially the difference is that a Touristica home is not meant to be occupied on a 100% basis but how that is policed is not known and in our particular area of Mazarron we have a Urbanisation that has some homes classified as Touristica but they are occupied full time by the owners without comeback.
Not sure at all why he should be trying to define the difference but you say in your first message that he is trying to impose sanctions on 'us' suggesting that you are not the only objector... if that is the case you really need to gather support for the EGM in order to object to what he is trying to 'impose'.
I will reiterate he cannot impose anything on anyone... the leading figure in the governing body of any community is the General Assembly, only they can make decisions and that includes you who have an equal right to anyone including the President.
By all means seek legal advice from a solicitor or perhaps go to see another administrator who I'm sure will back your thoughts if he sees a prospect of getting control of your urbanisation and I have known them make some robust interruptions at General Meetings to secure victory... would be difficult though if you are in a minority but if he really is trying to operate outside of legitimacy then it might make him think again
Good luck but at the end of the day the majority view will always prevail.
