The Vatican has classified the "attempted ordination" of women as one of the most serious crimes a Catholic priest can commit, putting it on a par with paedophilia, heresy and desecrating the Sacrament.
Anyone found to be ordaining women will be automatically excommunicated under the new rules.
The Vatican also announced new laws to tackle paedophilia, doubling the church's statute of limitations to 20 years and allowing bishops to sack priests without having to resort to a full canonical trial.
