I want to know the answer to the following question:
What did constitutional changes in 2007 prohibit?
All the background I'm provided with is that "Constitutional changes voted on 19 March 2007 prohibited parties from using religion as a basis for political activity, allowed the drafting of a new anti-terrorism law, authorised broad police powers of arrest and surveillance, and gave the president power to dissolve parliament and end judicial election monitoring.". Is that enough to answer the question?
Answer: yes
