Rabanan – Day ends at shkia (sunset)
Rebbe Yehuda – Day ends at Plag Hamincha (two and half halachic hours before shkia)

Based on the above rule according to the first explanation of our Gemara why before the בת קול ruled the halacha like beis hillel was it left to the volition of the individual to decide to follow beis hillel or beis shamai. Why were they not bound by the rule ספק דאורייתא לחומרא ספק דרבנן לקולא ?
