Amend HB 1161 by adding a new appropriately numbered section to read as follows, and renumbering existing sections accordingly: SECTION _____. Section 252.043(a), Local Government Code, is amended to read as follows: (a) If the competitive sealed bidding requirement applies to the contract, the contract must be awarded to the lowest responsible bidder. The governing body may reject any and all bids. A bid that has been opened may not be changed for the purpose of correcting an error in the bid price. This chapter does not change the common law right of a bidder to withdraw a bid due to a material mistake in the bid.
