Let's look at a few examples.
The LORD detests lying lips, but he delights in men who are truthful. (Pro 12:22 NIV)
You could suggest that this is wisdom literature, not law, and so carries the weight of what is good rather than what is necessary. So let's go to some law.
Do not lie. Do not deceive one another. (Lev 19:11 NIV)
Seems fairly clear. But you could suggest that this is the OT and perhaps there's more 'freedom' in the New Testament on these sorts of issues where wisdom suggests that bending the truth may perhaps bring a better outcome. So let's go to the NT.
Do not lie to each other, since you have taken off your old self with its practices and have put on the new self, which is being renewed in knowledge in the image of its Creator. (Col 3:9-10 NIV)
Now one could further again argue that perhaps there is an escape clause here in that the command seems to apply only to discussion within the Christian community. So Christians could technically lie, but only to non-Christians? Yet, lying in general seems to be a sin that God suggests leaves its exponents culpable:
But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars--their place will be in the fiery lake of burning sulphur. This is the second death." (Rev 21:8 NIV)
Now, I'm generally not one who likes to build my case based on one-verse prooftexts, but having been challenged to do so I don't think that the Scriptural evidence points away from my central thesis. Even if you're building your ethics from a very flat view of the 'divine command' approach, you're really going to struggle to think that it's godly to engage in any sort of deception without very serious prayer and reflection on why these commands might not apply in that particular case.
