Frequent disruptions and walkouts in the just-concluded Budget session of Parliament led to wastage of 115 working hours out of the 385 of both the Houses.

Parliamentary affairs minister P K Bansal said the Lok Sabha lost 70 hours or 36.6 per cent of its scheduled time due to walkouts and disruptions while Rajya Sabha lost 45 hours or 28 per cent of its time.

The session began on February 22 and ended on May 7 with a month-long recess.

"Total productive time in Lok Sabha was 138 hours or 66 per cent of scheduled time, while it was 130 hours, or 74 per cent, in Rajya Sabha," according to a report by PRS Legislative Research, a Delhi-based think tank.

During the Winter session in 2009, the productive time in Lok Sabha was 76 per cent and it was 88 per cent in the Rajya Sabha.

According to the report, bedlam over issues like price rise, 2G spectrum allocation, phone tapping, women's reservation bill, Maoist attack in Dantewada and the IPL controversy led to disruption of proceedings of the House for several days.

The government could only get six of the 27 planned bills cleared during this session, the biggest of the year.

Half of the bills were passed without discussion due to pandemonium on issues such as price rise, women's reservation bill and the IPL controversy, says the study.

The bills passed included the Tamil Nadu Legislative Councils Bill 2010, the Employees State Insurance (Amendment) Bill, 2009, and the National Green Tribunal Bill, 2009.

However, the session saw over 75 per cent attendance by MPs in both the houses, higher than the previous session.

The average attendance by MPs in Lok Sabha was 79 per cent, while it was 78 per cent in Rajya Sabha.

In the previous Winter session, the attendance was 66 per cent in the lower House and 68 per cent in the Upper House, says the report.
