I'm working on prestashop 1.5 that invalidates quantities under 10 for each product for professionals, note that profesionnals are customers linked to groups with ID 4 or 5.
the best solution i'did is:
1- Override CartController under override/controllers/front/CartController
2- Added this little snipet: (where 4 and 5 are groups ids) (target method is processChangeProductInCart then add your controle)
4- you can remark that later in the controller there's another quantity check made by prestashop using var called minimum_quantity, i didn't altered that code, i think it'sb not quiet careful to do it, since custom code have to be clear and separated from original code to avoid unwanted results
i hop it helps

$arr = $this->context->customer->getGroups();
$minQuantity = -1;
if(in_array(4,$arr) || in_array(5,$arr)) $minQuantity=10;
if($qty_to_check<$minQuantity)
$this->errors[] = Tools::displayError('Minimum order quantity is 10 for profesionnals');
3- be careful to add this code out of an if surrount that does not cover all scenarios, in our cas i've added it just after stock controle.4- you can remark that later in the controller there's another quantity check made by prestashop using var called minimum_quantity, i didn't altered that code, i think it'sb not quiet careful to do it, since custom code have to be clear and separated from original code to avoid unwanted results
