So-called ‘safe access zones’ within 100 metres of facilities providing abortions came into effect Thursday with those infringing facing substantial fines or imprisonment for up to six months .

It will mean that any kind of pro-life presence, including silent prayer vigils, that might influence a person’s decision to go for an abortion would fall afoul of the law.

People will get a Garda warning as a first-off to the commission of an offence and this means those who are unaware of the law and at risk of offending are informed that they are engaged in prohibited conduct and that continuation of this conduct will amount to an offence.

Penalties arising for offences can include fines or jailed for up to six months.

Penalties have been provided on an escalating basis where harsher penalties may apply for repeat offences, according to the legislation.
