It may not always be possible but that is not the case here. It is bad code, and the programmer needs to fix it. The easiest way for them would be for them to use a module. It would solve two issues, it makes them more flexible to new solutions, and there is a good chance that it will work better than anything that is home grown.

It is easy to say its corporate politics that prevents me from doing 'blah' and continue doing what you are doing.

I find that it leads to people who think they know more than they do, writing more code than they should and introducing bugs because of things they have not thought of before... And more than likely, they just did not ask!
