“Safe access zones” which criminalise people who impede access to abortion services come into effect on Thursday.

Such zones are in operation within 100 metres of the entrance and exits of premises where a GP, obstetrician or gynaecologist provide termination of pregnancy services.

This includes general practitioner clinics and family planning clinics as well as acute hospitals.

The Department of Health says the new laws ensure that people who access termination of pregnancy services can do so in “safety and with dignity, without fear of influence or intimidation”.

Within safe access zones, conduct aimed at impeding access or influencing decisions in relation to these services is now a criminal offence.

Anyone prosecuted for this offence and found guilty may face fines and imprisonment.

The legislation contains a requirement for a “garda warning” prior to the commission of an offence.

The department says this will ensure that people who are at risk of offending are made aware that they are engaged in prohibited conduct and that continuation of this conduct will amount to an offence.

It said: “This mechanism ensures that people have an opportunity to regulate their behaviour and avoid a criminal sanction.”

Health Minister Stephen Donnelly said the legislation addresses a need to support and protect people who require access to termination of pregnancy services.

“Patients who require these services are now legally protected from unsolicited influence, intimidation and pressure with a 100-metre zone of relevant healthcare premises,” he said.

“At a time when they are most in need of empathy and consideration, this law provides them with privacy and security.”
