Opposition party leaders and Senator Frances Black have called on the Government to enact the Occupied Territories Bill before the end of the year.
At a news conference at Leinster House this morning, they published a joint motion which also seeks to ensure that "services" are contained in the legislation, and not just goods.
Attending the event were Sinn Féin leader Mary Lou McDonald, Labour Party leader Ivana Bacik, Social Democrats leader Holly Cairns, People Before Profit/Solidarity's Richard Boyd Barrett, Green Party leader Roderic O'Gorman and Senator Black - who first introduced the legislation.
The joint motion will be debated during People Before Profit's private members' business time on Wednesday.
The Government has said it is working on its Occupied Territories Bill, which would limit trade with illegal Israeli settlements.
Deputy Boyd Barrett said it was possible that some countries, like the US or EU member states, are applying diplomatic pressure on the Government not to enact the Occupied Territories Bill
He said: "It's absolutely outrageous that the Government would give-in to that pressure."
The TD for Dún Laoghaire added that the Government had "... made a solemn commitment to the people of this country in the General Election [to enact the Bill]. They should honour that commitment. It's a simple as that."
Deputy McDonald described the Government as "serial offenders in terms of breaking their promises and breaking their word."
She said: "They have dragged their feet. They have delayed. They have prevaricated. And now is the time for action."
Senator Frances Black said she was "disappointed" that she had not heard back in recent weeks from Tánaiste Simon Harris about the passage of the legislation.
She said: "We need this done as soon as possible. It's absolutely urgent. And as others have said - we have an obligation to pass this bill, in its entirety, with goods and services."
Asked if there could be negative economic consequences flowing from passing the legislation, Ms Bacik said: "There is no clarity about any consequences ... indeed other countries, like Spain, that have moved much more swiftly, have not seen any such consequences. So I think it's contestable whether any such consequences would result."
Mr O'Gorman said economic issues surrounding the legislation had to be "looked at in the round", but it was also important that Ireland's foreign policy was "informed by our values."
He said: "The Occupied Territories Bill is a very meaningful step to try and prevent the deletion of a nation - that is the Palestinian nation ... where there has been an ongoing active attempt, despite the ceasefire in Gaza, to make it impossible for a Palestinian State [to be created] by the persistent erosion of Palestinian land and Palestinian farms and their replacement by [Israeli] settlements."
Ms Cairns said Opposition parties were "united behind Frances [Black's] bill and are calling on the Government to enact it", adding that other countries - Spain, Slovenia, the Netherlands and Demark - were leading on the issue.
She said it was "the very least we can do, when we're legally obliged to under the Genocide Convention."
The Cork South West TD said: "I think it is high time that this Government is held to account for what seems to be its empty promises, if you look at the [General] Election. Now they have an opportunity to show people that they will actually put their legislation where their mouth is."
