On behalf of is sometimes wrongly used where on the part of is intended. The distinction is that on behalf of someone means `for someone's benefit' or `representing someone', while on the part of someone can be roughly paraphrased as `by someone'. So, the following example is incorrect: another act of apparent negligence, this time not on behalf of the company itself, but on behalf of its banker , when what was meant was there was negligence by the company's banker
