Should GST be delayed?

ICAI wants that GST should be delayed in his press notice at ET 

" For smoother transition, it is imperative that GST be implemented from the first day of a financial year. Since there is very little time for the slated implementation date of April 1, 2010, it is recommended that GST be implemented from April 1, 2011.

Goods and Service tax is new revolution in Indirect tax. After applying this GST, all indirect tax like VAT, service tax, excise duty and other sale tax will be terminated. Govt. of India was planning to implement of Goods and Services Tax from 1st April 2010 . But ICAI wants GST rollout to be delayed by a year.

ICAI is giving argument that states governments are not ready for these changes.

 I think whatever ICAI says in press notice. Government of India should see the benefit  of assessee who is  facing difficulty by implementing different rules and regulation and should implement GST as soon as possible. But, Govt. should  safeguard against an increase in liability for suppliers involved in such contracts from an adverse impact of higher taxation rates under GST.
