Malcolm Chisholm, Labour MSP for Edinburgh Northern and Leith, said the legislation is driven entirely by finance.
"The cabinet secretary has been forced to modify a very bad Bill so it ends up simply as a bad Bill," he said.
"That doesn't alter the fact that it still is bad."
Tory MSP Annabel Goldie offered her support and said: "I'm glad that the cabinet secretary has yielded to his metaphorical beating over the head and improved what was a poor situation and made it somewhat better."
Mr MacAskill told Parliament: "These amendments reflect concerns expressed by members of the Law Society of Scotland that the original threshold of £68 might compromise access to justice."
