Anti-Austerity Alliance TD Paul Murphy said he "really wouldn't want to go to prison".
He was speaking almost a fortnight since controversy erupted over reports that he was among 20 people who could face charges as a result of a protest in the Jobstown area of Dublin last November.
No-one has yet been charged as a result of the incident.
Deputy Murphy said that defending himself against possible charges is not how he wants to spend his time.
"I really wouldn't want to go to prison," he said.
"I think anyone who would want to go to prison for whatever reason would be mad.
"I want to be spending my time campaigning on water charges, on housing, on all the issues that affect people, on building a very serious left alternative in this country.
"We're now going to have to invest resources and time in preparing to defend ourselves for what are incredible charges of false imprisonment for engaging in a sit-down protest."
