The way your query is worded it gives an impression of you being thoroughly misguided about the expectation of discipline from Govt servant. In you own interest you need to know that.
1. What action can be taken if I am pursuing higher education without permission?
YOU RENDER YOURSELF LIABLE FOR DISCIPLINARY ACTION WHICH CAN RESULT IN ANY PENALTY RANGING FROM “CENSURE” TO “DISMISSAL FROM SERVICE”
2. considering the point that will not avail the benefit of adding it in my service records.
THEN WHAT DO YOU GAIN BY ANNOYING DEPARTMENT. IF THE QUALIFCATION IS NOT ADDED (NOT POSSIBLE UNLESS PERMITTED BY THE DEPARTMENT) YOU ANNOT APPLY FOR ANY POST BASED ON SUCH QUALIFICATION.
3. Is it a crime to pursue higher education without permission liable to proceeded bother legally and departmentally?
YES. IT IS A DEPARTMENTAL MISCONDUCT
4. considering the point that our constitution gives us right to education.
THE SAME CONSITUTION EMPOWERS PRESIDENT TO FRAME SERVICE RULE AS PER PROVISIO TO ARTICLE 309. EXERCISING THESE POWERS SERVICE RULES ARE FRAMED WHICH ARE BINDING ON GOVT SERVANT.
THE CONSITITUTION ALSO EMPOWERS GOVT AND LEGISLATURE TO CURB FUNDAMENTAL RIGHTS BY “PROCEDURE ESTABLISHED BY LAW”. THE AFORESID RULES ARE “PROCEDURE ESTABLISHED BY LAW”.
FOR EXAMPLE CONSITUTION ALSO GIVES YOU A RIGHT TO CONTEST ELECTIONS (EQUL FOR ALL CITIZENS) . HOWEVER THE AFORESAID RULE FRAMED AS “PROCEDURE ESTABLISHED BY LAW”. PROHIBIT GOVT SERVANT FROM ANY POLITICAL ACTVITY EXCEPT (I) CASTING VOTE (II) ATTENDING PUBLIC MEETING (not a closed door meeting) OF CANDIDATES/PARTIES.
FOR EXAMPLE CONSIOTUTION ALLOWS EVERY PASSPORT HOLDER TO TRAVEL TO ANY COUNTRY ANY TIME (EQUAL FOR ALL NATIONAL). HOWEVER THE AFORESAID RULE FRAMED AS “PROCEDURE ESTABLISHED BY LAW”. PROHIBIT GOVT SERVANT FROM EVEN VISITING AN EMBASSY (INCLUDING CULTURAL WING) WITHOUT PERMISSION.
5. If the employer, (esp. govt. employer) create troubles for me after knowing the point what i can do to against my employer?
BEGGING FOR MERCY WILL BE THE ONLY OPTION.
