Sometimes authors toss out questions without answering them. For instance, in a journal article:
The view [of net neutrality] taken by the Council of Europe suggests that there should be a very strong presumption in favour of banning all discrimination unless it meets the very high threshold of “over-riding public interest”. That would inevitably lead to the question of how could prioritising Internet content ever fall under “over-riding public interest”? Considering that question is well beyond the scope of this article, but provides an interesting angle with which to examine the need for prioritisation.

You can search full-text law reviews on LexisNexis or Westlaw for indications in an article that the author has mentioned an interesting question in need of further research. Try phrases such as "open question," "interesting topic," or "article topic.

Casebooks & treatises: Scan the notes in casebooks (and especially recent casebook supplements) for comments that some issue is unresolved. Search treatises online for "open question" and similar phrases. Examples:
As discussed earlier, the United States Supreme Court recently upheld a restriction on the receipt of all publications to a group of highly recalcitrant prisoners in Pennsylvania's supermax prison. Whether or not the reasoning of that decision would apply more broadly to other prisoners in disciplinary confinement remains an open question. However, the justification offered in Beard for the restriction clearly would not apply for inmates in administrative segregation. Inmates are not in that restrictive environment for punishment; therefore, restrictions on receipt of literature should be much more carefully scrutinized

An interesting question Glass did not resolve is the status of a patent that issues with a specification that was not enabling as of its filing date but was enabling at the date it issued. In an infringement suit, should the court rule the patent invalid for failure to comply with Section 112? Or should it merely deprive the patent owner of the filing date as the presumptive date of invention in applying the novelty and nonobviousness requirements? The rationale of Glass seems to indicate that the former course should be followed. The applicant should make full enabling disclosure as of the date the specification is filed and should not be allowed to rely upon what others may later publish.

A call for papers is an announcement by editors of a journal or organizers of a conference that they are seeking papers on a given theme. Some calls for papers ask authors to send an abstract or proposal; others seek finished papers. Reading the call for papers can give you ideas for topics, whether or not you submit your own paper. And of course, if you do submit a paper, that can be a path to publication. If there is a conference, you could have a chance to present your paper and to interact with other scholars in the field.
The Legal Scholarship Blog lists conferences, symposiums, and calls for papers. You can search by topic, you can use the calendar to find upcoming paper deadlines, or you can simply browse the listings. Posts usually link to the journals' or conferences' websites for more information.
If you follow blogs on specific topics, you will often see calls for papers in those areas.
As with a call for papers, the topic description for a student writing competition can give you valuable ideas. Prizes for these competitions can include cash, publication in a journal, or travel expenses to a conference.
As you develop your topic, you will find it helpful to talk to your professors and to lawyers you have worked with. You will find the conversations are more constructive if you have already done some work. If you were Prof. Pundit, how would you respond to these two students?
Use your contacts. Go to professors and others to help you with your ideas. But go prepared; don't expect them to hand you a perfect topic.
