I can justify the placement of Dr.Shireen Mazari and Dr.Munazza Hassan above Fauzia Kasuri.As Asad Umar explained three criterion for the placement on reserved seats list.i-e
a)Loyality to and seniority in the party:Both Shireen Mazari and Munazza Hassan were in PTI way before 30th October 2011.Since Fouzia Kasuri is the founding member, so she might get few more points than the other two in this catagory.
b)Capability:Fauzia Kasuri is good in general political talks but she is not expert in any particular field of life.On the other hand, Shireen Mazari is Ph.D in strategic relations and defence affairs.She is must for PTI in the parliament when it comes to either foreign/defence policy formulation in the standing committee of NA or the debate on these issues in NA session.So, Shireen Mazari outweigh Fouizia Kasuri by huge marign in this catagory.Similarly, Munazza Hassan is a medical doctor and, in the absence of Dr.Yasmeen Rashid, she is must for debating health issues and/or policy formulation on health.
c).Intra-party elections:It was unfortunate that Fouzia Kasuri couldn't participate in intra-party elections due to her dual-nationality.It is to be remembered that single nationality requirement was not only from PTI side but it is also a constitutional requirement as per political parties ordinance 2001.So, Munazza Hassan, being the elected president outweigh both Shireen Mazari and Fouzia Kasuri in this catagory of merit.
Having said that, I regard Fouzia Kasuri very high and I hope that she will remain with the party.She can be accomodated in Senate elections of March 2015, 21 months away from now.
