If you want to do more complicated logic, then scenarios might not satisfy your needs. Then you can override method init and do all the logic that define validation rules over there, adding results to $validationRules array. And the in rules() method you just return that array. Something like that:

 class Person extends CActiveRecord
{
    public function init(){
        if( TRUE){
            $this->validationRules[] = array('first_name','required');
            $this->validationRules[] = array('last_name','required');
        }

    }

    public $validationRules = array(
        array('email', 'required'),
        array('email, email1, email2, email3', 'email', 'message'=>'Email format is invalid'),
        array('email, address, email1, email2, email3', 'length', 'max'=>255),

    );

    public function rules()
    {
        return $this->validationRules;
    }
}
