Question: Why are women *Pasul leEidus* ? 

Does this still apply?

Answer: 
Loosely translated from [Kipa.co.il](http://www.kipa.co.il/ask/show/204215-%D7%9E%D7%93%D7%95%D7%A2-%D7%90%D7%99%D7%A9%D7%94-%D7%A4%D7%A1%D7%95%D7%9C%D7%94-%D7%9C%D7%A2%D7%93%D7%95%D7%AA)

> Women are disqualified because of a *gezeirat haKatuv,* [an inference from the Biblical text], as the Rambam says in Hilchot Eidut 9:2, based on Devarim 16:6 and 19:15, where it uses the male gender, and not the female. Thus we see that women are *not* disqualified because of their competency or trustworthiness, rather because of a biblical verse.

> In addition, women are disqualified due to their honor\respect. A court does *not* have the right to subpoena women and subject them to interrogation. The flipside is that women are disqualified to testify, since they cannot be subjected to this disrepectful public appearance. In fact, in cases where the courts seek the testimony of women, messengers are sent to her home to perform the questioning, out of respect.

the first comment on the OP from @user4523 says brings the Ben Ish Chay's [answer](http://www.hebrewbooks.org/pdfpager.aspx?req=31373&st=&pgnum=196&hilite=) to your question 

from where it seems, in short, the main reason is that woman should stay at home and not be with men (since it might lead to promiscuity)  

if her testimony would be believed some woman would use it as an excuse for promiscuity (like saying that she was in privet with 3 men because she was giving testimony)

---

another reason is that this is part of the punishment (curse) for eating from the tree of knowledge
