Rare 'intensive' revision in Bihar four months before polls

The Election Commission's 'Special Intensive Revision' of Bihar's electoral rolls has ignited political debate, differing from past revisions. While intensive revisions aren't new, the timing of Bihar's SIR, months before assembly elections, is unusual. Unlike previous 'de novo' exercises, it builds upon the 2002-03 roll, incorporating new enumeration forms and document submission.
