This thread at the NO2ID forum has a few suggestions.
In addition Unity of the No2ID forum has posted the following at their blog, Tests of Integrity and Intent. Which goes in to greater depth of what they see as the second line of defence

1. Kill the Bill
2. Change the Bill to include much tighter constraints on Government, etc.
3. Resist using Civil Disobedience.
