The committee voted on the matter on Wednesday after more than four hours of testimony from officials involved in the SNC-Lavalin affair, including Prime Minister Justin Trudeau's former principal secretary, Gerald Butts.
Wilson-Raybould has claimed that a year ago she was put under pressure to order a deferred prosecution agreement for the Quebec-based engineering and construction firm's fraud and corruption charges, and that her refusal to do so led to her being shifted out of the attorney general post to the veterans' affairs portfolio.
On Wednesday, Wilson-Raybould issued a statement saying she is willing to offer further testimony on the matter to the House of Commons justice committee, following on from her February 27 hearing.
"It seems grossly unfair, with all due respect, that we were allowing Mr. Butts to come and talk about what happened after she [left] cabinet but she can't do so", NDP justice critic Murray Rankin said. A former health minister and Indigenous-services minister who was president of the federal Treasury Board when she quit the cabinet, Philpott was widely seen as one of Trudeau's most capable ministers.
His performance rivaled former attorney general Jody Wilson-Raybould's during her own appearance a week earlier, both in the level of detail and tone.
Butts also said the December 18 meeting was not urgent and that all Prince was told was that he couldn't see how seeking advice from someone like former Supreme Court chief justice Beverley McLachlin constituted political interference. "But I have to say, it's been a long time", Butts said, trailing off and pausing awkwardly for a second or two.
And while Wilson-Raybould said she made her final decision in mid-September to back the DPP's decision to proceed with a trial and that it was inappropriate for any lobbying to persist afterwards, Butts said he, and likely others in the PMO, only became aware of this while listening to her testimony to the committee.
SNC-Lavalin openly lobbied the Canadian government for an out-of-court settlement that would mean paying a fine and agreeing to compliance measures.

He denied making any veiled threats against Wilson-Raybould, as she had testified. Based on what Butts says in his testimony, things may improve for Trudeau - or they may not.
Trudeau has acknowledged raising the issue with Wilson-Raybould, but has said that was appropriate. If she deemed an agreement appropriate, the attorney general would then appoint another agent to negotiate it.
Butts stressed the decision to remove her from her post had nothing to do with SNC Lavalin and the decision to shuffle the cabinet was only made after MP Scott Brison told the Prime Minister he would not seek re-election.
Philpott said she would continue as a Parliament member for Trudeau's Liberal Party.
On the Prime Minister's website no cancellation has been announced, however an "update" to his itinerary has just one event scheduled for Toronto on Tuesday.
Canada's ethics commissioner is investigating the affair but that will take months.
Liberal justice committee member Randy Boissoinault said Butts' testimony was "very revealing", though opposition MPs were less impressed.
"How can you be credible to us when Ms Wilson-Raybould gave us such clear consistent testimony of a pattern of interference in an independent prosecution?" asked legislator Charlie Angus of the left-leaning New Democrats.
Asked to comment on Wernick's involvement in this matter, Butts said on Wednesday morning that he finds the accusations levelled against Canada's top civil servant "completely inconsistent with his character".
