Option to withdraw pending Settlement Commission applications allows abatement and continued assessment with limited exclusion of time-limits. The amendment permits an assessee to withdraw a pending Settlement Commission application within a prescribed short window by intimating the Assessing Officer; on withdrawal the Commission proceedings abate and the assessing authority shall proceed as if no application had been made, with a specified exclusion of the withdrawal period from limitation and interest computations. If not withdrawn, pending applications are deemed received by an Interim Board when allotted or transferred; the Board may allot or transfer applications between Interim Boards and shall receive all records and evidence from the Settlement Commission as its own. Assessing authorities are prohibited from using material produced by the assessee before the Commission in later proceedings, though material independently collected by authorities remains usable.
