1. CDT Reports Calls Pennsylvania Blocking Law Unconstitutional and Unsound

The Center for Democracy and Technology released a major report calling
unconstitutional a recent Pennsylvania law that forces Internet Service
Providers (ISPs) to block access to numerous web sites without adequate
court oversight. The report's release coincides with a request under
Pennsylvania's right-to-know law seeking records of the Attorney General's
previously undisclosed demands to block web sites pursuant to the law.

The CDT report - entitled "The Pennsylvania ISP Liability Law: An
Unconstitutional Prior Restraint and a Threat to the Stability of the
Internet" - analyzes a 2002 Pennsylvania law that forces ISPs to block
access to any web site deemed "child pornography" without notice to the
site's publisher and without any opportunity to challenge the determination.
ISPs are required to block the sites even if they do not host the content
and have no relationship whatsoever with the publishers of the content.
The Pennsylvania Attorney General has since gone even further, bypassing
the law's inadequate court procedures to simply demand by letter that
sites be blocked. The report argues that the statute, which blocks access
to sites that are wholly innocent, is an unconstitutional restriction on
speech, blocks access to sites that are wholly innocent.

------------------------------------
2. Background on the Penn. Web Blocking Law

Passed in early 2002, the Pennsylvania ISP Liability Law imposes potential
liability on ISPs for child pornography available on the Internet, even if
the ISPs are not hosting the offending content and have no relationship
whatsoever with the publishers of the content. Essentially, the law makes
any ISP doing business in Pennsylvania potentially liable for content
anywhere on the Internet.

Under the law, the state Attorney General or any county district attorney
can apply to a local judge for an order declaring that (a) certain content
on the Internet is probably child pornography, and (b) the content can be
reached through the services of a specified ISP. The entire court
proceeding occurs with the participation of just the government, with no
prior notice to the ISP or the web site owner required, and no notice
after the hearing to the web site owner. This kind of proceeding contrasts
with typical court proceedings that require notice to parties and an
opportunity for both sides to be heard.

Under the law, a judge does not make any final determination that the
challenged content is child pornography; instead, the judge needs only to
find that there is "probable cause" evidence of child pornography. Based
on this determination, the state Attorney General notifies the ISP in
question. The ISP then has five days in which to block all access to the
specified content, or else face criminal liability.

Critically, the ISP Liability Law imposes potential criminal liability
for content that is rely "accessible through" an ISP's or access
provider's service. The law lacks any requirement that the ISP have any
connection to or responsibility for the content (such as if the content
were created by the ISP or one of the ISP's customers). Instead, the
potential liability is created simply because - as with any Internet
service provided by any ISP - someone in Pennsylvania can reach content
located anywhere on the Internet.

------------------------------------
3. Laudable Goals, Serious Constitutional and Technical Problems

While acknowledging the grave nature of the problem of child pornography,
CDT's report details the serious problems - both legal and technical -
inherent in the law and the Attorney General's actions:

* CDT concludes that the law violates constitutional principles of free
   speech and due process, and is unconstitutional under both the First
   and Fourteenth Amendments of the U.S. Constitution.
* Because ISPs must block web sites based on their numeric "Internet
   Protocol" (IP) address, the law also blocks web sites that are completely
   unrelated to any child pornography sites, simply because most Internet
   web sites today share their IP addresses with many other wholly unrelated
   web sites.
* Because of how the Internet is structured, Pennsylvania's blocking orders
   reach far outside of the state and prevent people across the country from
   accessing lawful Internet content.
* The Pennsylvania law forces ISPs to manipulate the sensitive "routing
   tables" used to send communications around the Internet, increasing the
   risk of major Internet service outages.
* The law does nothing to remove the child pornography at its source or to
   prosecute the creators and posters of the content. The law merely attempts
   to shield Pennsylvania citizens from the content while allowing children
   to continue to be victimized in the production of the child pornography.


The magnitude of over-blocking under the Pennsylvania law is demonstrated
in a separate report - also released this week - by Benjamin Edelman of the
Berkman Center for Internet & Society at the Harvard Law School. In that
report, Edelman finds that more than two-thirds of all .COM, .NET, and .ORG
web sites share their IP addresses with at least fifty other web sites. Any
blocking order aimed at one of those web sites under the Pennsylvania law
would block all fifty (or more) sites, even if those sites are wholly
unrelated to the targeted web site.

In light of these findings, the effect of the law is like stopping mail
delivery for an entire apartment building because one tenant is accused
of wrongdoing. The law will prevent many Internet users around the country
from accessing hundreds or perhaps thousands of innocent web sites, with
no notice or explanation whatsoever.

Benjamin Edelman's report, entitled "Web Sites Sharing IP Addresses:
Prevalence and Significance," was released by Mr. Edelman this week, and
is available at http://cyber.law.harvard.edu/people/edelman/ip-sharing/.

4. Request Filed for Records of Undisclosed Web Site Blocking

In conjunction with the release of its report, CDT has also assisted in
the filing today of a Pennsylvania "Right to Know" Request to the Attorney
General, demanding that he disclose the hundreds of web sites that he has
blocked since the law went into effect. Professor Seth Kreimer of the
University of Pennsylvania Law School, with CDT as counsel, submitted the
"open records" request seeking all orders and notices served pursuant to
the law on ISPs by the Attorney General's office.

Under Pennsylvania's open records system, the Attorney General must
produce the requested documents within ten days. CDT will post the
response on our Web site when we receive it.
