The below code can help you. try it.

   $(function(){
    $.validator.addMethod('ifIsCrime',function(value, element){
         if($("#chckCrime").is(':checked') && $("#txtJustification").val()==""){
             return false;
         }return true;},'This is a required field');

    $('form').validate({
            rules: {
                txtJustification:{
                  ifIsCrime: true,
                },
            }
    });

});

Try adding your $.validator.addMethod AFTER $('form').validate.

Edit:

Also, I see that you haven't used the rule you've created, namely "ifIsCrime".

rules: {
                    txtJustification:{
                      required: true, ifIsCrime: true
                   }
        }

EDIT2: Demo

My bad, now that I understand what you need, I wouldn't suggest a custom function for your requirement.

You could do it by replacing required: true with, required: '#chckCrime:checked'.

For your reference: jQuery validate - set conditional rules based on user selection

and a demo:

<form id="form">
    <input class="form-control" type="text" id="test" placeholder="Click here to enter text" name="test" />
    <input type="checkbox" id="chckCrime" class="checkbox" name="chckCrime" /> 
    <input type="submit" value="Submit My Application" class="btn btn-primary pull-right">
</form>

JS being:

$(function(){
    $('#form').validate({
                rules: {
                    test:{
                      required: '#chckCrime:checked' 
                    }
                    }
        });
})
