Two visa application, which one is valid? first granted or last granted?

[auzeebujji]

Hi,
I'm applying for both 175 and 176 visa application. 175 thru Online and 176 thru paper based. My primary interest is on 175. I'm launching 176 app just as a contingency for flagged occupation scenario.

I want to know how the outcome of visa application would be for two cases. I heard two different statements saying that,
1. once the first visa (176) is approved, CO will straightaway reject the second 175 application when it get assigned to him.
2. I also heard that even though 176 is granted, 175 application can continue its regular journey and case officer may approve 175 in this case, once after 175 is granted 176 will be void.

Just want to hear if anybody personally experienced two visa application scenario and share their experience in this regards.
Thank you all for contribution in this forum, this is an excellent forum.

Whichever visa is granted last will supersede the one before it.
