Acts of Parliament
Tarzi sets this in the context of a power struggle between President Hamid Karzai and opposition forces in the Parliament, with the distribution of power within the Afghan political framework as the main issue. I'm not sure process issues are what's really driving this, though, as it could be simple factionalism between the Karzai regime and its opponents, with both blocks defined with little regard to ideology.
What's also troubling is what it could mean for Afghanistan's reconstruction. If you crack down on foreign interests, especially in ways that could affect their security, then they will eventually leave. However, Afghanistan still needs a lot of assistance from outside. If NGO's and foreign governments are in some manner driven away, then Afghanistan will be left to fend for itself just as surely as it was in the early 1990's.
