Seven groups representing immigrant rights held a protest outside the Dáil this morning against the new Immigration, Residence and Protection Bill.
The organisations described the legislation as draconian and said it would trample on civil rights.
Their main concern is a provision that allows for summary deportation of migrants without access to a fair hearing.
Current procedures give a person 15 days to make representations to the Minister as to why they should be allowed to remain in Ireland.
The groups said the new Bill would take away this provision.
The coalition of groups is also seeking the establishment of an independent appeals body, which would ensure that immigration procedures are carried out in a 'fair, transparent and efficient manner'.
They said that allowing for summary deportations is also contrary to 2008 Supreme Court rulings.
In a statement today, the groups said the Bill ignores a recommendation from the UN Human Rights Committee that urged Ireland to outlaw summary deportations.
'In Ireland we value fairness, transparency and due process. The Immigration Bill in its current form goes against these basic principles,' they said.
'By allowing summary deportation, the Bill denies minimum safeguards and tramples on an individual's civil and fundamental rights.
'We will not stand idly by and watch this draconian measure become law.'
