Long-time e-discovery practitioners have become accustomed to a number of accepted truths. For example, Excel files never look right when printed, processing data will take longer than you would like it to, and you should not wait until Friday night to submit a document production request to your vendor.

Recently, though, some aspects of e-discovery practice that have seemed well-settled have, well, seemed to return. Are privilege logs burdensome? (Yes, they can be.) Are 502(d) orders a good idea? (Yes, almost always.) Is there a right way do to TAR? (Yes, reasonably and proportionally.)
