Before Geoffrey Jackson of the governing body was questioned by the Australian Royal Commission, he was asked whether he wanted to swear on the Bible or take an affirmation; he chose to swear on the Bible. The present governing body of Jehovah's Witnesses (including Jackson) deems that swearing on the Bible is a matter of conscience!
w03 1/15 p. 21 Questions From Readers - "Is it Scripturally acceptable for a Christian to place his hand on the Bible and swear to tell the whole truth in court?" "Each individual must make a personal decision in this regard. (Galatians 6:5) However, there is no Biblical objection to taking an oath to tell the truth in court." (edited)
The governing body clearly practices what they themselves preach, rather than what the Bible teaches!
Their inspired expressions take precedence over Christ's.
(Matthew 5:34-37) "However, I say to you: Do not swear at all, neither by heaven, for it is God’s throne; nor by earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King. Do not swear by your head, since you cannot turn one hair white or black. Just let your word ‘Yes’ mean yes, your ‘No,’ no, for what goes beyond these [yes or no] is from the wicked one."
Which parts of "do not" and "at all" are hard to interpret or understand?
Using the governing body's reasoning, when Christians are told not to commit adultery, (Romans 2:22) it is in fact down to the individual's conscience to guide them!!!
