The office of the Lord Chancellor, Derry Irvine (pictured) has delayed publishing its findings into claims assessors until the end of this month.
Lord Irvine appointed Brian Blackwell to head the committee last June, in response to stories that the industry is rife with shoddy practice and poor advice.
It originally intended to publish the findings by the start of this year, but the committee has been unable to compile a report due to the heavy workload.
The Lord Chancellor's office has contacted a number of claims assessing firms regarding the investigation.
A spokeswoman for the Association of Personal Injury Lawyers (Apil) said: "While the delay is undoubtedly disappointing, the outcome is the important thing. Apil would welcome any decision which protects insured people from unqualified and unregulated claims assessors."
