Former junior minister Ivor Callely will be sentenced on Monday for fraudulently claiming mobile expenses at Leinster House while he was a senator.

Callely, 56, has pleaded guilty to four counts of using invoices believing them to be false instruments between November 2007 and December 2009 while he was a member of the Seanad.

The court heard he used invoices from defunct businesses to claim phone expenses under an Oireachtas Scheme which allows members to claim €750 every 18 months.

After he became aware of the scheme in August 2007, shortly after being appointed a senator, Callely began submitting for expenses at 18 months intervals.

He also submitted retrospective invoices from his time as a TD.

He fraudulently claimed a total of €4,207.45 using six invoices.

Callely was before Dublin Circuit Criminal Court today for sentencing.

Defence counsel Michael O'Higgins SC said his client has 25 years of public service behind him.

He said Callely has suffered greatly both personally and professionally because of the charges and asked Judge Mary Ellen  Judge Ring to consider imposing community service instead of a prison sentence.

Judge Ring remanded Callely on continuing bail until 28 July.

She requested counsel produce case law to guide her on the issue of whether Callely's former position in society is an aggravating factor.

The maximum term for the offence is ten years and an indeterminate fine.
