El The beginning of human life is at once in Colombia, in view of the ratification of the Optional Protocol on the Elimination of All Forms of Discrimination against Women, adopted by the UN General Assembly in 1999, ratified in 2005. The issue is developed in two judgments, the first, C-355 of 2006, decriminalises abortion in three exceptional situations: Rape, mother’s disease and foetus malformation. The second, T-388 of 2009 covers conscientious objection, which is only recognised to natural persons; affirming the highest Constitutional Court that it is not a right enjoyed by legal persons or the State, limiting to clinics, hospitals and health centres that raise conscientious objections to the non-execution of abortion. Failure to comply with this declaration has led to penalties being imposed on private health institutions for failure to comply with the erga ommes effects of the judgments handed down by the Constitutional Court; these institutions are calling for an objection of institutional conscience for their religious ideology and beliefs. These criteria have bioethical and biolegal implications compared to the pluralist philosophical, religious and legal interpretation of Article 18 of the Political Charter; which guarantees freedom of conscience in our social state based on the rule of law, and it is for the legislator to re-establish its competence through Biolaw.
