The legal debate on fetal rights sometimes invokes the notion of fetal viability .  Its primary determinant is fetal lung capacity which typically develops at twenty-three to twenty-four weeks.  The twenty-three weeks is usually regarded as the lower bound of fetal viability because technology has been unable to surpass the limit set by lung development.  It was nonetheless stated that technology has made it possible to regard the fetus as a patient independent of the mother.  In Winnipeg Child and Family Services v. G. , the judges argued that "technologies like real-time ultrasound , foetal heart monitors and foetoscopy can clearly show us that the foetus is alive" and thus the born alive rule is "outdated and indefensible". 
Over the past twenty years, Israel has taken measures to guarantee a nearly blanket exemption from its obligation under international law to pay compensation to Palestinians harmed by its security forces. In a new report released today (Wed., 8 March), B’Tselem traces the development of this practice and illustrates how it has led to a major drop in the number of claims for damages Palestinians filed in recent years. Israel’s policy reflects how little value it places on the lives, bodies and property of Palestinians living under its control.
