Hello,
Yashar koach for the question.
The background for this can be found in our ethical halachic essay on the Tzohar Ethics website.
I do not see grounds to give permission to lie in this case.
It is permissible to act against guidelines that are harmful, not universal, etc. Regarding this we say, “with the pure act purely, and with the perverse act wily”. However, the decision of the IDF regarding which cases are grounds for leave and which are not reasonable cases, even if there is room for discussion, is not an injustice, and therefore I have a difficult time seeing a permit to lie.
All the best and Yashar koach,
Rabbi Yuval Cherlow
Head of the Tzohar Ethics Center
