Code of Ethics and Code of Conduct

Code of ethics is a set of guidelines issued by an organisation to its employee to guide their conduct in accordance with its values and ethical standards. 

It is a set of principles that influence the judgement. In case an employee faced with ethical dilemmas, it helps guide his decision making.

For Example, All India Services (Conduct) Rules, 1968:

Every member of the Service shall maintain:-
(i) high ethical standards, integrity and honesty;
(ii) political neutrality;
(iii) promoting the principles of merit, fairness and impartiality
in the discharge of duties;
(iv) accountability and transparency;
(v) responsiveness to the public, particularly to the weaker
section;
(vi) courtesy and good behaviour with the public

For example, the Model Code of Conduct during Elections for the conduct of political parties and candidates during elections mainly with respect to speeches, polling day, polling booths, portfolios, election manifestos, processions and general conduct.

Code of Conduct for Civil Servants suggests dos and don'ts of being an officer. 

For example, Central Civil Services (Conduct) Rules, 1964 says 'no officer should criticise the Government or its decision through any medium or speech.'
