# How to keep LyX from using babel?

I'm writing a document using the `copernicus_discussions.cls` document class. This document class doesn't work when using `babel`. So I need to keep LyX from automatically using `babel`. However, even though in `Tools->Preferences->Language` I selected "Language package: None" and disabled all checkboxes on that page, and even though in my document preferences, I selected "Language package: None", the generated LaTeX source still contains the line

``````\usepackage{british,english]{babel}
``````

How can I prevent LyX from inserting that line?

What's wrong with using `babel` with `natbib`? – Joseph Wright Sep 27 '12 at 16:52
as I wrote in the question, the `copernicus_discussions.cls` class doesn't work in conjunction with both natbib and babel. More specifically, LaTeX gets sent into an infinite loop at the first `\citet` or `\citep` command. – andreas-h Sep 27 '12 at 17:18
I just realized it also happens when using `\cite`, so it's not `natbib` dependant – andreas-h Sep 28 '12 at 8:15
There used to be a Lyx mailinglist, some years ago I got a usefull answer there, my question then also aimed at Lyx internals. – Keks Dose Sep 28 '12 at 9:34

Workaround: In `Document Settings (Language)`, set language package to `Custom` and insert `% dummy` (or anything else preceded by a `%` char) into the custom package input widget.
