If two ships are on a shield boundary with each other and each only has one shield down, can transporters be used to move personnel between the two?

Yes. This assumes that both ship have willingly chosen their down shield to be the one facing the other ship this impulse.

Thanks. It would be great if something under the transporter section of the rules could indicate it (via the CRUL). The question came up in a game last night and we had ruled the opposite because there was no shield boundary language in the transporter rules. In other words, we incorrectly concluded that if either shield was down the transporter operation could occur.

These may not pertain to the situation but:
If--
1) Their not allied ships,
2) They fired on each other that impulse,
3) Then the shield facing has been designated for you already,

Otherwise each ship owner would designate at the point transporter
activities took place ---

Doesn't the shield chosen to face the enemy in the direct fire segment stay the same shield for the other functions segment?

Yes. However, if no such determination was made in the Direct Fire phase, it can be chosen in the Other Function phase.

Also, the initial example assumes that no other ships were at issue, and that the two ships were friendly. So, in their case, declaring which shields to use won't be made until the Other Functions phase.
