For headlines in a newspaper and/or other publications it is best to keep it as short as possible. For one thing I would drop the articles from the sentence. How about:

Government and Parliament’s intervention must be seperated from SOE

Without further context I cannot gaurantee that the headline I provided is factually correct, but it is based on the headline provided.

Restricting Governmental and Parliamentary Intervention Vis- a- Vis the SOE....

Or something like this constructed more tightly (e.g.,with more nouns, etc.)

Hands off SOE! (tabloid newspaper version)

For a more scholarly title (in a magazine), try

Government and Parliament should avoid interfering in SOE.

I'm a bit surprised that SOE is already plural. It would seem more natural to write "the SOE" or "SOEs" or "SOE sector".

In any case, to make titles punchy, avoid passives.
