Yes. The developers can not check any changes from their sandbox in until 
Requirements 2 and 3 have
been satisfied.  This however would risk loosing any known working states of 
the developers while
they rework.


Branches however help the developers stay sane while working under Requirements 
2 and 3.


with what little you have written, it sounds as if the organization either is 
suffering from
"Branch-a-holic"
http://www.cmcrossroads.com/bradapp/acme/branching/pitfalls.html#BranchAholic
or
"Merge-mania"
http://www.cmcrossroads.com/bradapp/acme/branching/pitfalls.html#MergeMania

and someone (you?) is trying to take them to a "Merge-a-phobia" state

 Brad Appleton has some decent ideas on how to work business practices 
(Requirements 2 and 3) into
configuration management systems

my guess at why your org is suffering either "Branch-a-holic" or "Merge-mania" 
is because you are
Branching per task:
http://www.cmcrossroads.com/bradapp/acme/branching/patterns.html#BranchPerTask
http://www.cmcrossroads.com/bradapp/acme/branching/branch-creation.html#BranchPerTask
instead of Branching per major task, with a smattering of "Personal Activity 
Branch"'s as
workers/task leads see fit:
http://www.cmcrossroads.com/bradapp/acme/branching/branch-creation.html#BranchPerMajorTask
http://www.cmcrossroads.com/bradapp/acme/branching/branch-creation.html#PersonalBranch
but these are only guesses with limited information, use at your own risk.
