At least Borland explicitly says you cannot do that:

"You can increase the visibility of a member in a descendant class by  
redeclaring it, but you cannot decrease its visibility. For example,  
a protected property can be made public in a descendant, but not  
private. Moreover, published members cannot become public in a  
descendant class."
