Create an event observer for event sales_quote_merge_before. Create a custom module and put this in config.xml.

<events>
 <sales_quote_merge_before>
 <observers>
 <cart_validation>
 <class>MyModule_CartValidation_Model_Observer</class>
 <method>quoteMergeBefore</method>
 </cart_update>
 </observers>
 </sales_quote_merge_before>

</events>

Create Observer.php in [MyModule]/[CartValidation]/Model and put this code.

class MyModule_CartValidation_Model_Observer 
 public function quoteMergeBefore($observer) 
 // Get Existing Cart Items
 $quoteItem = Mage::getSingleton('checkout/cart') - > getQuote() - > getItemsCollection();

 //Get current product trying to be added
 $product = Mage::getModel('catalog/product')
 - > load(Mage::app() - > getRequest() - > getParam('product', 0));

 /*
 * Your code logic to see restricted items in cart
 * 
 */
 $isRestricted = $this - > hasRestrictedItems($quoteItem, $product);
 if ($isRestricted) 
 Mage::getSingleton("core/session") - > addError("You can not add this product");
 return;
 

 

Make sure you implement your restricted products logic in hasRestrictedItems().
