If you are trying to do this on purpose, just set the `scriptPubKey` to `OP_RETURN` and nothing else.  This makes the transaction provably unspendable:  https://en.bitcoin.it/wiki/Script#Provably_Unspendable.2FPrunable_Outputs

If it made it into the blockchain, meaning 1 confirmation or more, it practically can't be invalidated. The same feature prevents people from reversing payments.

If it's provably unsolvable, then there's no way to spend the coins, and they're practically destroyed.
