Input: Consider Input: Four officers were named as part of the inquiry after police broke new regulations while trying to discover the identity of journalists' sources.
The deputy chief constable told the justice committee he would not invite them due to "critical legal issues".
Assistant Chief Constable Ruaraidh Nicolson will appear instead.
He will be questioned by MSPs on 12 January.
Deputy Chief Constable Neil Richardson previously told the committee that officers had "misinterpreted" a 22-day-old code of conduct over intercepting communications due to a "misjudgement".
A watchdog said Police Scotland's "failures" in the case "could properly be viewed as reckless".
Following the last meeting of the justice committee on the issue, four officers were named as being part of the inquiry and invited to give evidence - Det Supt David Donaldson, Det Insp Joanne Grant, Det Supt Brenda Smith, and Ch Supt Clark Cuzen.
However, Mr Richardson wrote to the committee saying "there clearly remain some critical legal issues, and particularly those touching on matters of competence, which are not yet fully resolved".
He said "while such matters remain unresolved and outstanding" he did not feel he was properly in a position to forward the committee's invitation to the four named officers, suggesting that Mr Nicolson appear instead.
Deputy convener Elaine Murray wrote back to Mr Richardson voicing disappointment, saying the committee would consider what further steps to take.
The investigation was sparked after the Interception of Communications Commissioner ruled that Police Scotland had obtained communications data without judicial approval on five occasions.
Sir Stanley Burnton said the "failures", made while police were trying to determine a journalist's source or an intermediary, could be viewed as "reckless".
The review is understood to relate to the murder of Emma Caldwell in 2005, after a re-investigation of the case was ordered in May 2015.
Police Scotland said "robust and rigorous steps" had been taken to comply with requirements in future.
During his evidence session in December, Mr Richardson named Mr Donaldson as an "extremely experienced officer" who had "misinterpreted" the new code of conduct, which had been in place for 22 days.
He said the "very aggressive" pace of change in bringing in the new guidance could have been a factor in the "error" subsequently made.
The policeman also hit out at some press coverage of the case, saying he had been portrayed as an "archetypal villain" and saying police had been unable to respond to many stories due to the live murder inquiry.

Output: Police Scotland has refused to let MSPs quiz four officers named in a Holyrood probe into breaches of new rules over intercepting communications.


Input: Consider Input: Benzema is being investigated for his part in an alleged plot to blackmail France team-mate Mathieu Valbuena.
The Real Madrid player - who denies wrongdoing - was not allowed to contact Valbuena, meaning they could not be in the same squad, but an appeals court has partially lifted some restrictions.
However Benzema, who is injured, was suspended from France duty in December.
That ban was due to stand until the end of court proceedings.
An investigating judge last month lifted the order keeping Benzema and Lyon playmaker Valbuena apart, but the prosecutor appealed. That was dismissed on Friday.
Benzema's lawyer, Sylvain Cormier, described the decision as "a first step".
The 28-year-old forward faces preliminary charges of conspiracy to blackmail relating to an extortion scam over a sex tape involving Valbuena.
If found guilty, he could face a minimum of five years in prison.
According to French media, Benzema mentioned a sex tape to Valbuena, 31, during a national team training session at Clairefontaine on 5 October.
Benzema told police he was advising a friend about what to do in a difficult situation.
But he could face charges for complicity in attempted blackmail and participation in a criminal conspiracy.

Output: Striker Karim Benzema will be eligible to play for France at Euro 2016 after some legal restrictions were lifted.


Input: Consider Input: The body of Helen Lancaster, 54, was found on Wednesday at the house in Kingston Road, Tewkesbury.
David John Lancaster, 59, of Kingston Road, was later arrested in Burnham-on-Sea, Somerset.
He was remanded in custody at Cheltenham Magistrates' Court to appear at Bristol Crown Court on Tuesday.
In a statement her family said they were "deeply saddened by the sudden loss of Helen".
"She will be greatly missed and was a much-loved mother, sister, daughter, aunty and friend."


Output: A man charged with murdering a woman whose body was found at a house in Gloucestershire, has been remanded in custody by magistrates.
