Trials are being halted and delayed as the service struggles to cope with cuts and an office shake-up.
Barristers have been continually before Plymouth Crown Court to apologise for the agency failing to meet deadlines for the service of case papers.
Now a lawyer has written to the court to apologise personally for delays in a case.
The CPS employee revealed they had a caseload of about 100 prosecutions to be prepared for trial in Plymouth, Exeter, Truro and Taunton.
Scores of staff have left the agency after its offices were centralised.
The Exeter-based lawyer said that they typically worked 7.30am until 6.30pm, regularly having no lunch break.
They have also worked unpaid weekends, Bank Holidays and days off.
The CPS has used a range of excuses to explain delays in cases, including “excessive workloads”, “resource issues” and “changing priorities between the four court centres”.
Independent barristers who prosecute Crown cases have told The Herald that the pressure of work on CPS lawyers was “lamentable”.
Staff often have to prepare hundreds of pages of evidence, working with the police and barristers for trials and responding to requests from courts and defence legal teams.
